[PATCH] qemu: Remove unnecessary variables and labels
by Kristina Hanicova 23 Nov '21

23 Nov '21

This patch removes variables such as 'ret', 'rc' and others which are easily replaced. Therefore, making the code look cleaner and easier to understand.

[PATCH v3 0/2] Fix /proc/*/stat parsing
by Martin Kletzander 23 Nov '21

23 Nov '21

While working on some polkit stuff I found out that we are inconsistent with the way we parse /proc/*/stat files, so I added a new helper instead along with some tests. Unfortunately using it for the thing I wanted is not really viable in the end, so it "violates" the Rule of three, but at least it does something correctly. v3: - Added an enum with names for the fields of the file - Made this not limited to linux as that was the way it worked in qemu before v2: - https://listman.redhat.com/archives/libvir-list/2021-November/msg00606.html - Fixed open64 by just using virFileReadAllQuiet instead of g_file_get_contents - Removed some leftover unused variables - Still do not know why my cirrus builds fail v1: - https://listman.redhat.com/archives/libvir-list/2021-November/msg00580.html Martin Kletzander (2): util: Add virProcessGetStat Use virProcessGetStat src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 34 ++----- src/util/virprocess.c | 125 +++++++++++++++++--------- src/util/virprocess.h | 66 ++++++++++++++ tests/meson.build | 1 + tests/virprocessstatdata/complex/stat | 2 + tests/virprocessstatdata/simple/stat | 1 + tests/virprocessstattest.c | 88 ++++++++++++++++++ 8 files changed, 249 insertions(+), 69 deletions(-) create mode 100644 tests/virprocessstatdata/complex/stat create mode 100644 tests/virprocessstatdata/simple/stat create mode 100644 tests/virprocessstattest.c -- 2.34.0

[PATCH 0/1] tools/bash-completion: fix variable leaks of "IFS" and "word"
by Koichi Murase 23 Nov '21

23 Nov '21

Description: The bash-completion function for virsh, which is defined in /usr/share/bash-completion/completions/virsh (generated from libvirt tools/bash-completion/vsh.in), overwrites the shell variables "IFS" and "word" on query for completions. Repeat-By: I am testing it with Fedora 35 Workstation where the completion script is provided by the package: libvirt-client-7.6.0-3.fc35.x86_64 With a Bash session with bash-completion loaded, one can observe the change of Bash behavior after the attempt of the completion for "virsh" command as follows: $ declare -p IFS | cat -A declare -- IFS=" ^I$ "$ $ virsh a[TAB][TAB] allocpages attach-device attach-disk attach-interface autostart $ virsh a[C-c] $ declare -p IFS | cat -A declare -- IFS="$ "$ Originally the value of IFS is IFS=$' \t\n', but it becomes IFS=$'\n' after the attempt of the completion. After that, word splitting of the shell will not be processed as normal: $ a='a b c' $ printf '<%s>\n' $a <a> <b> <c> $ virsh a[TAB][TAB][C-c] $ printf '<%s>\n' $a <a b c> The shell variable "word" is also affected by the virsh completion. Fix: The completion function "_virsh_complete" should declare "IFS" and "word" as local variables before changing them. Reference: I initially received the related issue in my project at https://github.com/akinomyoga/ble.sh/issues/147 -- Koichi Koichi Murase (1): bash-completion: fix variable leaks of "IFS" and "word" tools/bash-completion/vsh.in | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) -- 2.21.3

[PATCH] meson: fix cpuset_getaffinity() detection
by Roman Bogorodskiy 23 Nov '21

23 Nov '21

The cpuset_getaffinity() function is checked in sys/cpuset.h to see if BSD CPU affinity APIs are available. This check requires including sys/param.h to work properly, otherwise the test program fails with unrelated errors like: /usr/include/sys/cpuset.h:155:1: error: unknown type name '__BEGIN_DECLS' __BEGIN_DECLS ^ /usr/include/sys/cpuset.h:156:12: error: unknown type name 'cpusetid_t'; did you mean 'cpuset_t'? int cpuset(cpusetid_t *); and so forth.

[PATCH] meson: improve CPU affinity routines check
by Roman Bogorodskiy 23 Nov '21

23 Nov '21

Recently, FreeBSD has got sched_get/setaffinity(3) implementations and the sched.h header as well [1]. To make these routines visible, users have to define _WITH_CPU_SET_T. This breaks current detection. Specifically, meson sees the sched_getaffinity() symbol and defines WITH_SCHED_GETAFFINITY. This define unlocks Linux implementation of virProcessSetAffinity() and other functions, which fails to build on FreeBSD because cpu_set_t is not visible as _WITH_CPU_SET_T is not defined. For now, change detection to the following: - Instead of checking sched_getaffinity(), check if 'cpu_set_t' is available through sched.h - Explicitly check the sched.h header instead of assuming its presence if WITH_SCHED_SETSCHEDULER is defined 1: https://cgit.freebsd.org/src/commit/?id=43736b71dd051212d5c55be9fa21c459930… https://cgit.freebsd.org/src/commit/?id=160b4b922b6021848b6b48afc894d16b879… https://cgit.freebsd.org/src/commit/?id=90fa9705d5cd29cf11c5dc7319299788dec… Signed-off-by: Roman Bogorodskiy <bogorodskiy(a)gmail.com> --- meson.build | 4 +++- src/util/virprocess.c | 8 ++++---- 2 files changed, 7 insertions(+), 5 deletions(-) diff --git a/meson.build b/meson.build index 9022bcfdc9..e4f36e8574 100644 --- a/meson.build +++ b/meson.build @@ -553,7 +553,6 @@ functions = [ 'posix_fallocate', 'posix_memalign', 'prlimit', - 'sched_getaffinity', 'sched_setscheduler', 'setgroups', 'setns', @@ -602,6 +601,7 @@ headers = [ 'net/if.h', 'pty.h', 'pwd.h', + 'sched.h', 'sys/auxv.h', 'sys/ioctl.h', 'sys/mount.h', @@ -671,6 +671,8 @@ symbols = [ # Check for BSD approach for setting MAC addr [ 'net/if_dl.h', 'link_addr', '#include <sys/types.h>\n#include <sys/socket.h>' ], + + [ 'sched.h', 'cpu_set_t' ], ] if host_machine.system() == 'linux' diff --git a/src/util/virprocess.c b/src/util/virprocess.c index 6de3f36f52..81de90200e 100644 --- a/src/util/virprocess.c +++ b/src/util/virprocess.c @@ -35,7 +35,7 @@ # include <sys/time.h> # include <sys/resource.h> #endif -#if WITH_SCHED_SETSCHEDULER +#if WITH_SCHED_H # include <sched.h> #endif @@ -480,7 +480,7 @@ int virProcessKillPainfully(pid_t pid, bool force) return virProcessKillPainfullyDelay(pid, force, 0, false); } -#if WITH_SCHED_GETAFFINITY +#if WITH_DECL_CPU_SET_T int virProcessSetAffinity(pid_t pid, virBitmap *map, bool quiet) { @@ -626,7 +626,7 @@ virProcessGetAffinity(pid_t pid) return ret; } -#else /* WITH_SCHED_GETAFFINITY */ +#else /* WITH_DECL_CPU_SET_T */ int virProcessSetAffinity(pid_t pid G_GNUC_UNUSED, virBitmap *map G_GNUC_UNUSED, @@ -646,7 +646,7 @@ virProcessGetAffinity(pid_t pid G_GNUC_UNUSED) _("Process CPU affinity is not supported on this platform")); return NULL; } -#endif /* WITH_SCHED_GETAFFINITY */ +#endif /* WITH_DECL_CPU_SET_T */ int virProcessGetPids(pid_t pid, size_t *npids, pid_t **pids) -- 2.33.1
