* gaih_inet: Split simple gethostbyname into its own functionSiddhesh Poyarekar2022-03-221-63/+64
| | | | | | | | Add a free_at flag in gaih_result to indicate if res.at needs to be freed by the caller. Signed-off-by: Siddhesh Poyarekar <siddhesh@sourceware.org> Reviewed-by: DJ Delorie <dj@redhat.com>
* 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.

* gaih_inet: Simplify service resolutionSiddhesh Poyarekar2022-03-221-100/+78
| | | | | | | | | | Refactor the code to split out the service resolution code into a separate function. Allocate the service tuples array just once to the size of the typeproto array, thus avoiding the unnecessary pointer chasing and stack allocations.

* getaddrinfo: Fix leak with AI_ALL [BZ #28852]Siddhesh Poyarekar2022-03-221-9/+25
| | | | | | | | | | | | | Use realloc in convert_hostent_to_gaih_addrtuple and fix up pointers in the result list so that a single block is maintained for hostbyname3_r/hostbyname2_r and freed in gaih_inet. This result is never merged with any other results, since the hosts database does not permit merging. Resolves BZ #28852.

* gaih_inet: Simplify canon name resolutionSiddhesh Poyarekar2022-03-221-55/+75

* Simplify allocations and fix merge and continue actions [BZ #28931]Siddhesh Poyarekar2022-03-225-52/+750
| | | | | | | | | | | | | | | | | | | | | 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: Protect against errno changes in function lookup (bug 28953)Florian Weimer2022-03-114-4/+142
| | | | | | | | | | | | | dlopen may clobber errno. The nss_test_errno module uses an ELF constructor to achieve that, but there could be internal errors during dlopen that cause this, too. Therefore, the NSS framework has to guard against such errno clobbers. __nss_module_get_function is currently the only function that calls __nss_module_load, so it is sufficient to save and restore errno around this call.

| | | | | | | | | | | | | | | | | | | | | | | | The _IO_wfile_overflow does not check if the write pointer for wide data is valid before access, different than _IO_file_overflow. This leads to crash on some cases, as described by bug 28828. The minimal sequence to produce the crash was: #include <stdio.h> #include <wchar.h> int main (int ac, char **av) { setvbuf (stdout, NULL, _IOLBF, 0); fgetwc (stdin); fputwc (10, stdout); /*CRASH HERE!*/ return 0; } The "fgetwc(stdin);" is necessary since it triggers the bug by setting the flag _IO_CURRENTLY_PUTTING on stdout indirectly (file wfileops.c, function _IO_wfile_underflow, line 213).
