Subject: [PATCH] qemu-nbd: Ignore SIGPIPE
|
||||
|
||||
qemu proper has done so for 13 years
|
||||
(8a7ddc38a60648257dc0645ab4a05b33d6040063), qemu-img and qemu-io have
|
||||
done so for four years (526eda14a68d5b3596be715505289b541288ef2a).
|
||||
Ignoring this signal is especially important in qemu-nbd because
|
||||
otherwise a client can easily take down the qemu-nbd server by dropping
|
||||
the connection when the server wants to send something, for example:
|
||||
|
||||
$ qemu-nbd -x foo -f raw -t null-co:// &
|
||||
[1] 12726
|
||||
$ qemu-io -c quit nbd://localhost/bar
|
||||
can't open device nbd://localhost/bar: No export with name 'bar' available
|
||||
[1] + 12726 broken pipe qemu-nbd -x foo -f raw -t null-co://
|
||||
|
||||
In this case, the client sends an NBD_OPT_ABORT and closes the
|
||||
connection (because it is not required to wait for a reply), but the
|
||||
server replies with an NBD_REP_ACK (because it is required to reply).

Don't reinvent a broken wheel, just use the hexdump function we have.

Impact: low, broken code doesn't run unless you have debug logging

Subject: [PATCH] exec: use qemu_ram_ptr_length to access guest ram
|
||||
|
||||
When accessing guest's ram block during DMA operation, use
|
||||
'qemu_ram_ptr_length' to get ram block pointer. It ensures
|
||||
that DMA operation of given length is possible; And avoids
|
||||
any OOB memory access situations.

From: Prasad J Pandit <pjp@fedoraproject.org>
|

|
||||
While parsing dhcp options string in 'dhcp_decode', if an options'
|
||||
length 'len' appeared towards the end of 'bp_vend' array, ensuing
|
||||
read could lead to an OOB memory access issue. Add check to avoid it.
