2020-02-12mips: Use 'long int' and 'long long int' in linux syscall codeWANG Xuerui
Style fixes only, no functional change.
2020-02-12alpha: Use generic gettimeofday implementationAdhemerval Zanella
It makes alpha no longer reports information about a system-wide time zone and moves the version logic on the alpha implementation. Checked on a build and check-abi for alpha-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de>
2020-02-12sunrpc: Properly clean up if tst-udp-timeout failsMatheus Castanho
The macro TEST_VERIFY_EXIT is used several times on sunrpc/tst-udp-timeout to exit the test if a condition evaluates to false. The side effect is that the code to terminate the RPC server process is not executed when the program calls exit, so that sub-process stays alive. This commit registers a clean up function with atexit to kill the server process before exiting the main program. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
2020-02-12elf: avoid stack allocation in dl_open_workerDavid Kilroy
As the sort was removed, there's no need to keep a separate map of links. Instead, when relocating objects iterate over l_initfini directly. This allows us to remove the loop copying l_initfini elements into map. We still need a loop to identify the first and last elements that need relocation. Tested by running the testsuite on x86_64.
2020-02-12elf: avoid redundant sort in dlopenDavid Kilroy
l_initfini is already sorted by dependency in _dl_map_object_deps(), so avoid sorting again in dl_open_worker(). Tested by running the testsuite on x86_64.
2020-02-12elf: Allow dlopen of filter object to work [BZ #16272]David Kilroy
There are two fixes that are needed to be able to dlopen filter objects. First _dl_map_object_deps cannot assume that map will be at the beginning of l_searchlist.r_list[], as filtees are inserted before map. Secondly dl_open_worker needs to ensure that filtees get relocated. In _dl_map_object_deps: * avoiding removing relocation dependencies of map by setting l_reserved to 0 and otherwise processing the rest of the search list. * ensure that map remains at the beginning of l_initfini - the list of things that need initialisation (and destruction). Do this by splitting the copy up. This may not be required, but matches the initialization order without dlopen. Modify dl_open_worker to relocate the objects in new->l_inifini. new->l_initfini is constructed in _dl_map_object_deps, and lists the objects that need initialization and destruction. Originally the list of objects in new->l_next are relocated. All of these objects should also be included in new->l_initfini (both lists are populated with dependencies in _dl_map_object_deps). We can't use new->l_prev to pick up filtees, as during a recursive dlopen from an interposed malloc call, l->prev can contain objects that are not ready for relocation. Add tests to verify that symbols resolve to the filtee implementation when auxiliary and filter objects are used, both as a normal link and when dlopen'd. Tested by running the testsuite on x86_64.

Linux 5.5 renames RWF_WRITE_LIFE_NOT_SET to RWH_WRITE_LIFE_NOT_SET, with the old name kept as an alias. This patch makes the corresponding change in glibc. Tested for x86_64.

2020-02-12Linux: Emulate fchmodat with AT_SYMLINK_NOFOLLOW using O_PATH [BZ #14578]Florian Weimer
/proc/self/fd files are special and chmod on O_PATH descriptors in that directory operates on the symbolic link itself (like lchmod).

2020-02-12Add internal <file_change_detection.h> header fileFlorian Weimer
The code started out with bits form resolv/resolv_conf.c, but it was enhanced to deal with directories and FIFOs in a more predictable manner. A test case is included as well. This will be used to implement the /etc/resolv.conf change detection. This currently lives in a header file only. Once there are multiple users, the implementations should be moved into C files.

900778283ac3 ("htl: make pthread_spin_lock really spin") made pthread_spin_lock really spin and not block, but the current users of __pthread_spin_lock were assuming that it blocks, i.e. they use it as a lightweight mutex fitting in just one int. __pthread_spin_wait provides that support back.

2020-02-10Use --disable-gdbserver in build-many-glibcs.py.Joseph Myers
Now that binutils-gdb has gdbserver at top level, an extra --disable-gdbserver configure option is needed when configuring binutils from a git checkout to avoid it also building gdbserver unnecessarily (although fairly harmlessly). This patch updates the options used in build-many-glibcs.py accordingly (although this might end up not being needed depending on what happens regarding whether gdbserver gets built for host != target). Tested with a build-many-glibcs.py compilers build for aarch64-linux-gnu using binutils-gdb master.
