I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
2021-09-03Remove "Contributed by" linesSiddhesh Poyarekar
We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2021-07-22mtrace: Wean away from malloc hooksSiddhesh Poyarekar
Wean mtrace away from the malloc hooks and move them into the debug DSO. Split the API away from the implementation so that we can add the API to libc.so as well as libc_malloc_debug.so, with the libc implementations being empty. Update localplt data since memalign no longer has any callers after this change. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
2021-07-22Move malloc hooks into a compat DSOSiddhesh Poyarekar
Remove all malloc hook uses from core malloc functions and move it into a new library libc_malloc_debug.so. With this, the hooks now no longer have any effect on the core library. libc_malloc_debug.so is a malloc interposer that needs to be preloaded to get hooks functionality back so that the debugging features that depend on the hooks, i.e. malloc-check, mcheck and mtrace work again. Without the preloaded DSO these debugging features will be nops. These features will be ported away from hooks in subsequent patches. Similarly, legacy applications that need hooks functionality need to preload libc_malloc_debug.so. The symbols exported by libc_malloc_debug.so are maintained at exactly the same version as libc.so. Finally, static binaries will no longer be able to use malloc debugging features since they cannot preload the debugging DSO.

2021-07-03mtrace: Deprecate mallwatch and tr_breakSiddhesh Poyarekar
The variable and function pair appear to provide a way for users to set conditional breakpoints in mtrace when a specific address is returned by the allocator. This can be achieved by using conditional breakpoints in gdb so it is redundant. There is no documentation of this interface in the manual either, so it appears to have been a hack that got added to debug malloc. Deprecate these symbols and do not call tr_break anymore.

2019-04-09malloc: Set and reset all hooks for tracing (Bug 16573)Carlos O'Donell
If an error occurs during the tracing operation, particularly during a call to lock_and_info() which calls _dl_addr, we may end up calling back into the malloc-subsystem and relock the loader lock and deadlock. For all intents and purposes the call to _dl_addr can call any of the malloc family API functions and so we should disable all tracing before calling such loader functions. This is similar to the strategy that the new malloc tracer takes when calling the real malloc, namely that all tracing ceases at the boundary to the real function and any faults at that point are the purvue of the library (though the new tracer does this on a per-thread basis in an MT-safe fashion). Since the new tracer and the hook deprecation are not yet complete we must fix these issues where we can. Tested on x86_64 with no regressions.

2017-08-08Do not use __ptr_t.Joseph Myers
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

2015-09-08Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).Joseph Myers
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway.

2012-11-19muntrace: reset file and hooks before finalizing the streamPino Toscano
fclose will call free, invoking its hook, then fprintf which would indirectly try to allocate a buffer, and this can cause malloc to be used (thus its hook to be invoked) if libio uses malloc instead of mmap; given any malloc/free hook locks the internal lock, this leads to a deadlock. To prevent this hook roundtrip at muntrace, first unset MALLSTREAM and the hooks, and only after that close the trace file.
