Package: general Severity: important X-Debbugs-Cc: br...@clisp.org I'm using Debian GNU/Linux on hppa, in a virtual machine emulated by QEMU 8.0.2. $ uname -srm Linux 6.3.0-2-parisc parisc
In this machine, for the invocation of any program, the length of the command line (= all arguments together) is limited to less than 3544 bytes. How to reproduce: In bash: $ /bin/echo `seq 913` -bash: /bin/echo: Argument list too long In dash: $ /bin/echo `seq 913` dash: 1: /bin/echo: Argument list too long I also see this while doing "make check" of packages that have more than 1000 tests. So, it appears to be a general problem. The values returned by getconf don't match the reality: $ getconf ARG_MAX 2097152 $ getconf _POSIX_ARG_MAX 2097152 I have looked at the values of several files in /sys/kernel and /proc/sys/kernel, without finding the cause. For comparison, in a different VM, running "Linux 6.3.7-t2 parisc" (from the T2-SDE distribution), I don't observe this bug. Both machines have the same amount of "physical" RAM: 256 MiB. The ulimit values don't appear to be the cause, because they are similar in the two machines: In the Debian VM (with the bug): $ ulimit -a real-time non-blocking time (microseconds, -R) unlimited core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 849 max locked memory (kbytes, -l) 65536 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 849 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited In the T2-SDE machine, with no bug: $ ulimit -a real-time non-blocking time (microseconds, -R) unlimited core file size (blocks, -c) 1048575 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 909 max locked memory (kbytes, -l) 8192 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 909 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
