Wed Mar 20 23:31:55 UTC 2019 - Marcus Rueckert <mrueckert@suse.de>
- update to 2.0.13
- Add BFD build option to keepalived.spec rpm file
Issue #1114 identified that the keepalived.spec file was not being
generated to build BFD support even if keepalived had been configured
to support it.
- Copy tarball to rpmbuild/SOURCES when building in place
It seems that even when building in place, rpmbuild expects the
tarball to be in the rpmbuild/SOURCES directory.
- Fix configure check for __always_inline
- Handle interface MAC addresses changing
When an interface is added to a bond interface, if it is the first
interface added, the MAC address of the bond interface is changed
to the MAC address of the added interface. When subsequent interfaces
are added, their MAC addresses are changed to that of the bond
interface.
Issue #1112 identified that if a bond interface is deleted and
recreated, the gratuitous ARPs were sent with the wrong source MAC
address.
This commit now updates interface MAC addresses from the netlink
RTM_NEWLINK messages, so that the correct MAC address is always
used.
- Minor tidying up of opening gratuitous ARP socket.
- Streamline setting SOCK_NONBLOCK on vrrp sockets.
- Use netlink reported hardware address length for unsolicited NAs
ETH_ALEN is correct for Ethernet type interaces, but is not right
for Infiniband interfaces.
- Minor tidying up of opening gratuitous NA socket.
- Make gratuitous ARP/NA sockets non blocking
keepalived shouldn't block when sending gratutious ARP/NA messages.
It is better to lose the messages than for keepalived to block, so
set the sockets non blocking.
- Use netlink provided broadcast address for gratuitous ARP
If an interface has a non-standard broadcast address, we should
honour it.
- Fix building on pre 3.10 kernels re track_process
Issue #1119 reported that keepalived wouldn't build on CentOS 6.
Various PROC_EVENT_- declarations were assumed to exist, some of which
were not introduced until Linux v3.10. Most of them are not needed, but
PROC_EVENT_COMM is used by the track_process code.
This commit now checks for the existence of the PROC_EVENT_- declarations,
but since keepalived uses PROC_EVENT_COMM, track_process is not supported
prior to Linux v3.2.
- Make track_process work prior to Linux 3.2, but with limitations
Prior to Linux 3.2 the PROC_EVENT_COMM event did not exist, which
means that keepalived is unable to detect changes to process name
(/proc/PID/comm) prior to Linux 3.2. most processes do not change
their process name, and so using track_process prior to Linux 3.2
is safe so long as the monitored processes are known not to change
their process name.
- Stop configure failing when nftables is not supported.
- Streamline socket use with linkbeat.
Previously the socket used for ioctls was opened and closed twice per
poll if using MII or ETHTOOL polling, and once per poll if using ioctl
polling. This commit opens the socket once at startup, uses that socket
for all linkbeat polls, and closes it on termination.
- Enable linkbeat polling to work with dynamic interfaces.
- Add linkbeat_interfaces configuration block
It was not possible to indicate that an interface that wasn't used
as the interface of a vrrp instance, but was used either as a track
interface, or for virtual/static ip addresses or routes should use
linkbeat. This commit adds that capability.
- Add ability to specify linkbeat type in linkbeat_interfaces block.
- Add --disable-linkbeat configure option
Does anyone use linkbeat anymore? This commit enables keepalived to
be build without the linkbeat code.
- Don't remove link local IPv6 address from VMAC that isn't keepalived's
If IFLA_INET6_ADDR_GEN_MODE isn't supported and a macvlan interface
already had a (non-default) link local addresss and the link local
address that matched the interface's MAC address was added, keepalived
was removing it as soon as it was added. This commit stop keepalived
removing the address when we shouldn't.
- Set configure init type correctly in keepalived.spec file.
- Fix handling of VMACs with multiple reloads
If a configuration is loaded that has a VRRP instance using a VMAC,
then the configuration is updated to remove that VRRP instance and
keepalived reloads its configuration, then the configuration is
updated again to reinstate the VRRP instance and the configuration
is again reloaded, keepalived thought the VMAC interface still
existed, whereas it was deleted following the first reload.
This commit ensures that keepalived properly detects whether an
interface exists following a reload.
- Remember more than one interface local address per interface
Keepalived needs a local address for each interface it sends adverts
on. If the address keepalived is using is deleted and another address
is configured on the interface, then keepalived should start using
that address. To do this, a list of configured address on each
interfaces needs to be maintained.
- Don't consider VIPs as local addresses when restart after crash
Keepalived maintains a list of addresses per interface that can be
used as source adddresses for adverts. To build the list, keepalived
reads the addresses configured on interfaces when it starts. However,
if keepalived crashed it will have left VIPs configured on interfaces,
and we don't want to use them as advert source addresses.
This commit makes keepalived compare the addresses on interfaces
to VIPs, and ignores any addresses that are VIPs.
- Fix removing left over VIPs at startup.
- Use read_timer() when parsing config where appropriate.
- Allow fractional warmup, delay_loop and delay_before_retry for checkers
To shorten the real server monitoring interval, make it possible to specify
decimal value for following items:
warmup
delay_loop
delay_before_retry
- Update connect_timeout configuration options
Based on the patch submitted by tamu.0.0.tamu@gmail.com this patch
allows setting the connect_timeout to a resolution of micro-seconds.
The patch also adds the ability to set a default value at the virtual
server and real server levels.
- Fix unused variable warning when building only with RFC compliant
SNMP.
- It enable to set zero value as mintime for delay_loop and connect_timeout.
- Add option not to check for EINTR if using signalfd()
If keepalived is using signalfd(), there are no asynchronous signal
handlers, and therefore EINTR cannot be returned.
Currently the check for EINTR is enabled by default, and configure
option --disable-eintr-debug disables the check, while
--enable-eintr-debug enables writing log entries if EINTR is returned.
Once sufficient testing has been performed, the default will be
changed not to test for EINTR if signalfd() is supported.
- Make checking for EAGAIN/EWOULDBLOCK consistent
The code in some places checked errno for EAGAIN and EWOULDBLOCK
and in other places only checked EAGAIN. On Linux EAGAIN == EWOULDBLOCK,
so the check is not necessary, but EAGAIN is not guaranteed to be the
same value as EWOULDBLOCK, so define check_EAGAIN that only checks EAGAIN
if they are the same value, but checks both if they are different.
- Ensure default connection timeout for smtp checker hosts set.
- Set default connection timeout if no smtp check host specified.
- Fix min timer value, zero to 0.000001Sec.
- Add fixing min time for vs_co_timeout_handler() and rs_co_timeout_handler().
- Fix parameter of read_timer(), it treat Mintime and Maxtime as microseconds.
- vrrp: vrrp_dispatcher_read() performance extension
We took time with Quentin to simulate and rework this code. We introduced
2 imbricated while loop:
(1) First one is catching recvfrom EINTR (this code trig
only on kernel older than 2.6.22 where signalfd was firstly introduced).
Newer kernel will immediately break the loop (hey guys: if you are running
older than 2.6.22 it is worth considering upgrading).
(2) Second loop will continue reading from socket until same VRID advert
has been received during the same cycle. After simulating, it appears that
during contention with a lot of VRRP instances (around 1500), this design
is needed to relax socket recvq from growing. This can be viewed as a
Poll-Mode activation during contention and fallback to regular I/O MUX
during normal operations. This loop breaks immediately and re-submit
opration to I/O MUX when there is no more to be read.
- Fix conversion from long for double in read_timer().
- Remove variable timer of unsigned long cast in read_timer().
When Double type variable timer is cast to long type, it's scale falls.
- changes from2.0.12
- Documentation related.
Remove keepalived.conf.SYNOPSIS content to make a pointer to manpage.
Update README manifest to reflect actual Keepalived goal and features.
- Improve error message if process events connector not enabled in
kernel.
- Add option to disable track-process functionality
Issue #1099 reported that their kernel did not support the proc events
connector, and it would therefore be helpful to have an option to build
keepalived without the track-process functionality.
This commit adds the --disable-track-process configure option.
- Fix vrrp instances going to fault state when have virtual routes
If an interface going down caused a vrrp instance to go to fault
state, and the vrrp instance also had virtual routes, the state
of the vrrp instance would be set to backup when the deletion of
the virtual route was detected. This commit ensures that the vrrp
instance stays in fault state until the interface is brought up
again.
- Remove Red Hat Linux 9 and RH Enterprise Linux 3 from spec file.
Red Hat Linux 9 and Red Hat Enterprise Linux 3 are both based on
Linux 2.4, which is no longer supported by keepalived. The options
in the spec file for Reh Hat Linux 9 have twice caused people to
specify wrong options to configure when trying to build keepalived,
so the options are removed to i) avoid confusion and ii) they are
not longer relevant.
- Add global option vrrp_min_garp.
By default keepalived sends 5 gratuitous ARP/NA messages after
transitioning to master, and 5 more 5 seconds later. This isn't
necessary with modern switches, and so if the vrrp_min_garp option
is set, only one gratuitious ARP/NA message is sent after transition
to master, and no repeat messages are sent 4 seconds later.
- Standardise definition of _INCLUDE_UNUSED_CODE_
- Remove out of date comment re VRRP over IPv6.
- Correct typo in keepalived.conf.5.
- Directly use structure sizes for packet header lengths.
- vrrp_state_fault_rx() is not used.
Wrap the function in conditional compilation so it is not compiled
- Convert so list loops to use LIST_FOREACH.
- Don't recalculate vrrp packet header address.
vrrp_get_header() calculates the address of the vrrp header in a
received packet, but it was being recalculated in vrrp_in_chk().
This commit passes the already calculated address to vrrp_in_chk().
- Ensure a received packet has an AH header if and only if AH auth.
Ensure that a received packet has an AH header if we expect AH
authentication, and doesn't have an AH header if we don't expect
AH authentication.
- Ensure all protocol headers received before return pointer to vrrp header
vrrp_get_header() returns a pointer to the vrrp header, but it now returns
NULL if insufficient data has been received to include all the (IP,
possibly AH, and VRRP) headers (this does not include the VIPs in the VRRP
packet).
This means that when a pointer to the VRRP header is returned, all fields in
all protocol headers can safely be accessed.
- Add check of received IPv6 hop count in multicast adverts
The VRRP RFC requires that IPv6 hop count MUST be checked to be 255,
just as the TTL for IPv6 must be 255. Previously that wasn't being
checked, since IPv6 raw sockets don't provide access to the IPv6
header.
Using recvmsg() rather than recvfrom(), and setting socket option
IPV6_RECVHOPLIMIT allows keepalived to receive the hop count as
ancillary data, and that can now be checked.
- Improve reading from vrrp receive sockets.
Previously no check was made of the return value from recvfrom()/
recvmsg(). This meant than an error could occur (e.g. EINTR), or no
data might be returned, and keepalived would still attempt to process
the receive buffer as though data had been received.
- Enhance and streamline checking of validity of received VRRP packet
This includes checking that a packet is multicast, unless unicast is
expected in which case it is checked for unicast, ensuring that if
AH authentication is used, the next header protocol is VRRP.
The sequence of some checks is revised to ensure that the fields being
checked are valid to be accessed prior to accessing them, e.g. check
that the packet is VRRP version 2 before checking the authentication.
- Stop clearing receive buffer before receiving VRRP packets.
This is no longer necessary now that the appropriate checks are
made of the return status of recvmsg(), and also that the checks
of received packet length and packet headers now do all necessary
checks.
- Add compile time checks for IPV6_RECVHOPLIMIT/IPV6_RECVPKTINFO
support.
- Update keepalived.spec.in build-requires.
The kernel package required for building keepalived is kernel-headers
not kernel-devel. Also, it is superfluous to have package kernel in
the build-requires!
- Add missing file (build.setup) to tarball.
- Fix calculating print format to rlim_t in configure.ac.
- Fix compiler warnings on 32 bit systems re HASH_UPDATE.
Removing all the casts stopped the warnings.
- Use PRI_rlim_t when printing rlim_t types.
- Use %zd/%zu for ssize_t/size_t to avoid warnings on 32 bit systems.
- Fix some space/tab formatting.
- Stop declaring some timer definitions unsigned to stop compiler
warnings.
TIMER_HZ, TIMER_CENTI_HZ, NSEC_PER_SEC were causing some compiler warnings
on some systems due to being defined with a 'U' unsigned suffix. Removing
the unsigned specifier stopped the compiler warnings.
- Fix compiler warning due to incorrect format specifier.
An int64_t should use % PRIi64 and not %ld
- Stop an uninitialized variable compiler warning.
- Fix MEM_CHECK debugging on processors without unaligned memory
access.
- Don't attempt to use unopened socket for getting ipset version.
- Tidy up an error message.
- vrrp: make vrrp_dispatcher_read() async while catching error.
During investigations we decided to update previous patch to resubmit
into I/O MUX on read error. It will make read procedure I/O MUX freindly
by removing potential sync operation potentially leading to a global
I/O MUX desync. We aggreed, the situation is really and very exceptionnal
but could happen.
- vrrp: vrrp_arp_thread split.
Split the function for maintainability purpose.
