similar to: [PATCH common] mlutils: Simple wrapper around sysconf (_SC_NPROCESSORS_ONLN).

statfs::f_type is usually a signed type, so cast it to unsigned to check its value against magic values of filesystems. --- common/mlutils/unix_utils-c.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/common/mlutils/unix_utils-c.c b/common/mlutils/unix_utils-c.c index f8c4f8abe..2afdc9e5f 100644 --- a/common/mlutils/unix_utils-c.c +++ b/common/mlutils/unix_utils-c.c @@

v2 -> v3: - Drop gnulib fallback.

This helps mkinitrd which runs pigz (parallel gzip). Thanks Jean-Louis Dupond for suggesting this change. --- common | 2 +- v2v/v2v.ml | 2 ++ 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/common b/common index c840f2e39..ea5278bba 160000 --- a/common +++ b/common @@ -1 +1 @@ -Subproject commit c840f2e39d0bb637a98b224c89f6df011e1d4414 +Subproject commit

The sysconf branch only contains a single commit: [klibc] Framework and trivial implementation of sysconf(3) The sysconf() function is required by libkcapi. I use libkcapi in my klibc based initramfs in order to decrypt the file system key for my rootfs. Can somebody merge this commit into master? After that I would like to send further patches required by libkcapi. regards Christian

Hi Everyone, I'm working on GCC112, which is POWER System S822 (Power8) machine running CentOS 7 machine (https://gcc.gnu.org/wiki/CompileFarm): $ cat /etc/centos-release CentOS Linux release 7.3.1611 (AltArch) I'm trying to determine L1 data cache size. When the following code runs it returns 0. The man pages state -1 is an error, so I think its claiming to succeed.

https://bugzilla.mindrot.org/show_bug.cgi?id=3735 Bug ID: 3735 Summary: The ngroups variable may be set to a negative value when calling sysconf(_SC_NGROUPS_MAX) Product: Portable OpenSSH Version: 9.8p1 Hardware: Other OS: All Status: NEW Severity: normal Priority: P5

Currently samba (2.0.6) relies on the NGROUPS_MAX define. This makes the number of allowed simultaneous (per-user) secondary groups a compile-time decision. $ find . -name \*.c | xargs grep NGROUPS ./source/lib/system.c: if (setlen > NGROUPS_MAX) { ./source/lib/replace.c: gid_t grouplst[NGROUPS_MAX]; ./source/lib/replace.c: while (i < NGROUPS_MAX &&

So it didn't make any noticable difference in my test. I wonder if the test guest I'm using (Fedora 32 using dracut) doesn't use parallel compression? However I don't think it can cause a problem and it seems obvious that it could benefit some cases. Rich.

Create a module ‘C_utils’ containing functions like ‘drive_name’ and ‘shell_unquote’ which come from the C utilities. The new directory ‘common/mlutils’ also contains the ‘Unix_utils’ wrappers around POSIX functions missing from the OCaml stdlib. --- .gitignore | 3 + Makefile.am | 24 ++--- builder/Makefile.am

v1 -> v2: - Removed the f_type field from StatVFS.statvfs structure. - New function StatVFS.filesystem_is_remote, written in C. [Thinking about it, this should probably be called ?is_network_filesystem?, but I can change that before pushing]. - Use statvfs instead of fstatvfs, and statfs instead of fstatfs. - Rejigged the comments in builder/builder.ml to make them simpler

The C function mkdtemp(3) requires that the string ends with 6 'X' characters, so appending a non-empty suffix causes the function to raise EINVAL. Luckily we only ever called this function with the last parameter "". --- builder/builder.ml | 2 +- builder/sigchecker.ml | 2 +- common/mlutils/unix_utils.ml | 4 ++--

I am working on a project that uses OpenMP along with Xen''s VCPU hotplug feature. The OpenMP libraries are used for writing multi-threaded applications, and they have a function named omp_get_num_procs() that is used to determine the number of processors available on the system. I noticed that when using the xm vcpu-set command in Xen to change the number of vcpus assigned to a domU
