||||||
|
jsc#PED-2877).

Thu Feb 23 21:24:45 UTC 2023 - Giuliano Belinassi <giuliano.belinassi@suse.com>
|
||||||
|
|
||||||
|
- Update package with libpulp-0.2.8:
|
||||||
|
* Minor code refactoring.
|
||||||
|
* Fixed a bug where libpulp rejected correct ELF files as library input.
|
||||||
|
* Fixed a file descriptor leak when -check-stack is passed to ulp.
|
||||||
|
* Fixed a bug where ulp did not shown libcrypto.so.1.1 as a livepatchable library (bsc#1208575)
|
||||||
|
|
||||||
|
-------------------------------------------------------------------
|

|
Mon Jan 2 19:53:55 UTC 2023 - Giuliano Belinassi <giuliano.belinassi@suse.com>
|
||||||
|
|
||||||
|
- Update package with libpulp-0.2.7:
|
||||||
|
* Add support to library to JSON library dumps, Removing any requirement of
|
||||||
|
adding the original library .so file into the livepatch build tarball.
|
||||||
|
* Update the ulp post hook script for transactional systems (jsc#PED-1078).
|
||||||
|
* Add `setup_package.sh` as part of libpulp tools.
|
||||||
|
|

Thu Nov 10 18:00:41 UTC 2022 - Giuliano Belinassi <giuliano.belinassi@suse.com>
|
||||||
|
|
||||||
|
- Update package with libpulp-0.2.6
|
||||||
|
* Add new `-R` option to specify a prefix root for livepatches
|
||||||
|
(jsc#PED-1078).
|
||||||
|
|
||||||
|
-------------------------------------------------------------------

|
Wed Aug 18 12:23:31 UTC 2022 - Giuliano Belinassi <giuliano.belinassi@suse.com>
|
||||||
|
|
||||||
|
- Update package with libpulp-0.2.5.
|
||||||
|
* Fix ulp tool not patching on highly stressed environments. The reason behind
|
||||||
|
it is that a 10s timeout was not enough depending of how stressed the
|
||||||
|
machine is. Worse cases when libpulp is running in a VM (bsc#1200316).
|
||||||
|
* Fix HANA testcase failures (bsc#1200129).
|
||||||
|
* Add support for searching for patches recursively. Previous versions only
|
||||||
|
searched on the path specified, ignoring subdirectories.
|
||||||
|
* Improve patching performance. Previous version took up to 20s ~ 25s to
|
||||||
|
patch 4000 processes. This version reduces this time to 6s. The way this
|
||||||
|
is done is reducing ptrace calls and switching to process_vm_readv/writev
|
||||||
|
when possible, and moving process discovery to a different thread.
