* gaih_inet: make numeric lookup a separate routineSiddhesh Poyarekar2022-03-221-439/+452
| | | | | | | | | | | | | Introduce the gaih_result structure and general paradigm for cleanups that follow to process the lookup request and return a result. A lookup function (like text_to_binary_address), should return an integer error code and set members of gaih_result based on what it finds. If the function does not have a result and no errors have occurred during the lookup, it should return 0 and res.at should be set to NULL, allowing a subsequent function to do the lookup until we run out of options.

* Simplify allocations and fix merge and continue actions [BZ #28931]Siddhesh Poyarekar2022-03-221-52/+91
| | | | | | | | | | | | | | | | | | | | | Allocations for address tuples is currently a bit confusing because of the pointer chasing through PAT, making it hard to observe the sequence in which allocations have been made. Narrow scope of the pointer chasing through PAT so that it is only used where necessary. This also tightens actions behaviour with the hosts database in getaddrinfo to comply with the manual text. The "continue" action discards previous results and the "merge" action results in an immedate lookup failure. Consequently, chaining of allocations across modules is no longer necessary, thus opening up cleanup opportunities. A test has been added that checks some combinations to ensure that they work correctly.

* getcwd: Set errno to ERANGE for size == 1 (CVE-2021-3999)Siddhesh Poyarekar2022-01-241-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No valid path returned by getcwd would fit into 1 byte, so reject the size early and return NULL with errno set to ERANGE. This change is prompted by CVE-2021-3999, which describes a single byte buffer underflow and overflow when all of the following conditions are met: - The buffer size (i.e. the second argument of getcwd) is 1 byte - The current working directory is too long - '/' is also mounted on the current working directory Sequence of events: - In sysdeps/unix/sysv/linux/getcwd.c, the syscall returns ENAMETOOLONG because the linux kernel checks for name length before it checks buffer size - The code falls back to the generic getcwd in sysdeps/posix - In the generic func, the buf[0] is set to '\0' on line 250 - this while loop on line 262 is bypassed: while (!(thisdev == rootdev && thisino == rootino)) since the rootfs (/) is bind mounted onto the directory and the flow goes on to line 449, where it puts a '/' in the byte before the buffer. - Finally on line 458, it moves 2 bytes (the underflowed byte and the '\0') to the buf[0] and buf[1], resulting in a 1 byte buffer overflow. - buf is returned on line 469 and errno is not set.

* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-038-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* posix: Add posix_spawn_file_actions_addclosefrom_npAdhemerval Zanella2021-07-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a way to close a range of file descriptors on posix_spawn as a new file action. The API is similar to the one provided by Solaris 11 [1], where the file action causes the all open file descriptors greater than or equal to input on to be closed when the new process is spawned. The function posix_spawn_file_actions_addclosefrom_np is safe to be implemented by iterating over /proc/self/fd, since the Linux spawni.c helper process does not use CLONE_FILES, so its has own file descriptor table and any failure (in /proc operation) aborts the process creation and returns an error to the caller. I am aware that this file action might be redundant to the current approach of POSIX in promoting O_CLOEXEC in more interfaces. However O_CLOEXEC is still not the default and for some specific usages, the caller needs to close all possible file descriptors to avoid them leaking. Some examples are CPython (discussed in BZ#10353) and OpenJDK jspawnhelper [2] (where OpenJDK spawns a helper process to exactly closes all file descriptors). Most likely any environment which calls functions that might open file descriptor under the hood and aim to use posix_spawn might face the same requirement. Checked on x86_64-linux-gnu and i686-linux-gnu on kernel 5.11 and 4.15.

| | | | | | | | | | | | | | | | Now that pthread_kill is provided by libc.so it is possible to implement the generic POSIX implementation as 'pthread_kill(pthread_self(), sig)'. For Linux implementation, pthread_kill read the targeting TID from the TCB. For raise, this it not possible because it would make raise fail when issue after vfork (where creates the resulting process has a different TID from the parent, but its TCB is not updated as for pthread_create). To make raise use pthread_kill, it is make usable from vfork by getting the target thread id through gettid syscall. Checked on x86_64-linux-gnu and aarch64-linux-gnu.
* Add C2X timespec_getresJoseph Myers2021-05-171-0/+1
| | | | | | | | | | | | | | | | | | | ISO C2X adds a timespec_getres function alongside the C11 timespec_get, with functionality similar to that of POSIX clock_getres (including allowing a NULL pointer to be passed to the function). Implement this function for glibc, similarly to the implementation of timespec_get. This includes a basic test like that of timespec_get, but no documentation in the manual, given that TIME_UTC and timespec_get aren't documented in the manual at all. The handling of 64-bit time follows that in timespec_get; people maintaining patch series for 64-bit time will need to update them accordingly (to export __timespec_getres64, redirect calls in time.h and run the test for _TIME_BITS=64). Tested for x86_64 and x86, and (previous version; only testcase differs) with build-many-glibcs.py.

* nss: fix nss_database_lookup2's alternate handling [BZ #27416]DJ Delorie2021-03-091-3/+1
| | | | | | | | | | | | | | | | | | | | __nss_database_lookup2's extra arguments were left unused in the nsswitch reloading patch set; this broke compat (default config ignored) and shadow files (secondary name ignored) which relies on these fallbacks. This patch adds in the previous behavior by correcting the initialization of the database list to reflect the fallbacks. This means that the nss_database_lookup2 interface no longer needs to be passed the fallback info, so API and callers were adjusted. Since all callers needed to be edited anyway, the calls were changed from __nss_database_lookup2 to the faster __nss_database_get. This was an intended optimization which was deferred during the initial lookup changes to avoid touching so many files. The test case verifies that compat targets work (passwd) and that the default configuration works (group). Tested on x86-64.
* linux: Require /dev/shm as the shared memory file systemFlorian Weimer2021-02-085-116/+17
| | | | | | | | | | | | | | | | | | | | | Previously, glibc would pick an arbitrary tmpfs file system from /proc/mounts if /dev/shm was not available. This could lead to an unsuitable file system being picked for the backing storage for shm_open, sem_open, and related functions. This patch introduces a new function, __shm_get_name, which builds the file name under the appropriate (now hard-coded) directory. It is called from the various shm_* and sem_* function. Unlike the SHM_GET_NAME macro it replaces, the callers handle the return values and errno updates. shm-directory.c is moved directly into the posix subdirectory because it can be implemented directly using POSIX functionality. It resides in libc because it is needed by both librt and nptl/htl. In the sem_open implementation, tmpfname is initialized directly from a string constant. This happens to remove one alloca call.
