[PATCH] process.c (proc_getgroups, proc_setgroups): use ALLOCV_N

Added by normalperson (Eric Wong) about 11 years ago. Updated almost 11 years ago.

Status:
Closed
Assignee:
normalperson (Eric Wong)
Target version:
2.2.0
ruby -v:
ruby 2.2.0dev (2014-05-19 trunk 46010) [x86_64-linux]
Backport:
2.0.0: DONE, 2.1: DONE
[ruby-core:62694]

Description

On my Linux system, these may return up to 64K rb_gid_t entries for
a total of 256K stack usage, potentially triggering SystemStackError
or just a segfault. Use ALLOCV_N for stack safety, especially since
these are not performance-critical methods.

Will commit in a day or two.
