glibc 2.34 moved all pthread functions into the main libc library. And it changed the (in memory) path of the main libc library to libc.so.6 (before it was libc-2.xx.so). This breaks various standard suppressions for helgrind and drd. Fix this by doing a configure check for whether we are using glibc 2.34 by checking whether pthread_create is in libc instead of in libpthread. If we are using glibc then define GLIBC_LIBC_PATH and GLIBC_LIBPTHREAD_PATH variables that point to the (regexp) path of the library that contains all libc functions and pthread functions (which will be the same path for glibc 2.34+). Rename glibc-2.34567-NPTL-helgrind.supp to glibc-2.X-helgrind.supp.in and glibc-2.X-drd.supp to glibc-2.X-drd.supp.in and replace the GLIBC_LIBC_PATH and GLIBC_LIBPTHREAD_PATH at configure time. The same could be done for the glibc-2.X.supp.in file, but hasn't yet because it looks like most suppressions in that file are obsolete.

# glibc-2.X specific
|
|
# These are generic cover-alls which catch a lot of stuff
|
|
# in various combinations of ld, libc and libpthread
|
|
#
|
|
# Note this is heavyhanded and not very clever:
|
|
#
|
|
# - suppress anything that has its top frame in ld.so
|
|
# That's fine, since it's mostly dynamic linking stuff,
|
|
# which has various deliberate (harmless) races
|
|
#
|
|
# - suppress anything that has its top frame in libc.so.
|
|
# This really isn't clever, since it could hide some
|
|
# legitimate races. But the problem is, if we don't do
|
|
# this, then loads of errors to do with stdio are reported, because
|
|
# H fails to see glibc's internal locking/unlocking of FILE*s
|
|
# as required by POSIX. A better solution is needed.
|
|
#
|
|
# - some of the stdio functions in newer glibc manipulate stdio
|
|
# FILE*s state through mempcpy, which we intercept, so we also need
|
|
# to suppress such manipulations.

# NPTL's pthread_cond_signal. Why only one stack frame -- at least we

|
# the glibc-2.5 sources) and does not create a proper stack frame.
