* getaddrinfo: Refactor code for readabilitySiddhesh Poyarekar2022-03-231-12/+33
| | | | | | | | The close_retry goto jump is confusing and clumsy to read, so refactor the code a bit to make it easier to follow. Signed-off-by: Siddhesh Poyarekar <siddhesh@sourceware.org> Reviewed-by: DJ Delorie <dj@redhat.com>
* gai_init: Avoid jumping from if condition to its else counterpartSiddhesh Poyarekar2022-03-221-250/+248
| | | | | | | | | | | Clean up another antipattern where code flows from an if condition to its else counterpart with a goto. Most of the change in this patch is whitespace-only; a `git diff -b` ought to show the actual logic changes.

* 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.

* 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.

* Remove stat wrapper functions, move them to exported symbolsAdhemerval Zanella2020-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the stat, stat64, lstat, lstat64, fstat, fstat64, fstatat, and fstatat64 static wrapper and add the symbol on the libc with the expected names. Both the prototypes of the internal symbol linked by the static wrappers and the inline redirectors are also removed from the installed sys/stat.h header file. The wrapper implementation license LGPL exception is also removed since it is no longer statically linked to binaries. Internally the _STAT_VER* definitions are moved to a arch-specific xstatver.h file. The internal defines that redirects internals {f}stat{at} to their {f}xstat{at} counterparts are removed for Linux (!NO_RTLD_HIDDEN). Hurd still requires them since {f}stat{at} pulls extra objects that makes the loader build fail otherwise (I haven't dig into why exactly). Checked with a build for all affected ABIs.

* nss: Turn __nss_database_lookup into a compatibility symbolFlorian Weimer2019-05-151-3/+3
| | | | | | | | | | | | | The function uses the internal service_user type, so it is not really usable from the outside of glibc. Rename the function to __nss_database_lookup2 for internal use, and change __nss_database_lookup to always indicate failure to the caller. __nss_next already was a compatibility symbol. The new implementation always fails and no longer calls __nss_next2. unscd, the alternative nscd implementation, does not use __nss_database_lookup, so it is not affected by this change.

* CVE-2016-10739: getaddrinfo: Fully parse IPv4 address strings [BZ #20018]Florian Weimer2019-01-211-1/+1
| | | | | | | | | | | | | | | | The IPv4 address parser in the getaddrinfo function is changed so that it does not ignore trailing whitespace and all characters after it. For backwards compatibility, the getaddrinfo function still recognizes legacy name syntax, such as 192.000.002.010 interpreted as 192.0.2.8 (octal). This commit does not change the behavior of inet_addr and inet_aton. gethostbyname already had additional sanity checks (but is switched over to the new __inet_aton_exact function for completeness as well). To avoid sending the problematic query names over DNS, commit 6ca53a2453598804a2559a548a08424fca96434a ("resolv: Do not send queries for non-host-names in nss_dns [BZ #24112]") is needed.

* Fix -Os feof_unlocked linknamespace, localplt issues (bug 15105, bug 19463).Joseph Myers2018-02-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for feof_unlocked. The usual approach is followed of adding __feof_unlocked (inlined when feof_unlocked is), making calls use it when required for namespace reasons, and using libc_hidden_proto / libc_hidden_weak for the feof_unlocked weak alias when only localplt but not namespace issues are involved. In the case of getaddrinfo.c, use of __feof_unlocked needs to be conditional since that code is also used in nscd (where __feof_unlocked is not available). Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed.

| | | | | | | | | | | | struct resolv_context objects provide a temporary resolver context which does not change during a name lookup operation. Only when the outmost context is created, the stub resolver configuration is verified to be current (at present, only against previous res_init calls). Subsequent attempts to obtain the context will reuse the result of the initial verification operation. struct resolv_context can also be extended in the future to store data which needs to be deallocated during thread cancellation.
