* libc: fix some overflow scenarios in vis(3)Kyle Evans2023-08-081-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | The previous incarnation of this would call wcrtomb() on the destination buffer, and only check for overflow *after* it's happened. Additionally, the conversion error / VIS_NOLOCALE path also didn't check for overflow, and the overflow check at the end didn't account for the fact that we still need to write a NUL terminator afterward. Start by only doing the multibyte conversion into mbdst directly if we have enough buffer space to guarantee it'll fit. An additional MB_CUR_MAX buffer has been stashed on the stack to write into if we're cutting it close at the end of the buffer, since we don't really have a good way to determine the length of the wchar_t without just doing the conversion. We'll do the conversion into the buffer that's guaranteed to fit, then copy it over if the copy won't overflow. The byte-for-byte overflow is a little bit easier, as we simply check for overflow with each byte written and make sure we can still NUL terminate after. Tests added to exercise these edge cases.

* t_setrlimit: Adjust resource limit to 20MDawid Gorecki2021-12-201-0/+4
| | | | | | | | | | | | | With ASLR enabled by default, RLIMIT_STACK test fails due to the fact that default stack gap can be as big as 15M. Because of that the resource limit of 4M results in test program receiving SIGSEGV immediately after exiting the setrlimit syscall. Since the idea of this test is to check if rlim_cur does not extend past rlim_max, adjusting the resource limit to 20M should not invalidate the test results.

This fixes problems like capsicumized tests not being able to open the file on exit. However, this test closes all file descriptors just to check that socketpair returns fd 3+4 and thereby also closes the ATF results file. This then results in an EBADF when writing the result so the test is reported as broken. While system calls that create new file descriptors (must?) use the lowest available file descriptor number, it does not seem useful to test this property here. Drop the check for FD==3/4 to unbreak the testsuite. We could also try to re-open the results file in ATF if we get a EBADF error, but that will fail when running under Capsicum.

* Significantly speed up libthr/mutex_test and make more reliableAlex Richardson2020-11-261-15/+100
| | | | | | | | | | | | | | | | | | | | | | | | Instead of using a simple global++ as the data race, with this change we perform the increment by loading the global, delaying for a bit and then storing back the incremented value. If I move the increment outside of the mutex protected range, I can now see the data race with only 100 iterations on amd64 in almost all cases. Before this change such a racy test almost always passed with < 100,000 iterations and only reliably failed with the current limit of 10 million. I noticed this poorly written test because the mutex:mutex{2,3} and timedmutex:mutex{2,3} tests were always timing out on our CheriBSD Jenkins. Writing good concurrency tests is hard so I won't attempt to do so, but this change should make the test more likely to fail if pthread_mutex_lock is not implemented correctly while also significantly reducing the time it takes to run these four tests. It will also reduce the time it takes for QEMU RISC-V testsuite runs by almost 40 minutes (out of currently 7 hours).

* regex(3): Interpret many escaped ordinary characters as EESCAPEKyle Evans2020-07-292-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In IEEE 1003.1-2008 [1] and earlier revisions, BRE/ERE grammar allows for any character to be escaped, but "ORD_CHAR preceded by an unescaped <backslash> character [gives undefined results]". Historically, we've interpreted an escaped ordinary character as the ordinary character itself. This becomes problematic when some extensions give special meanings to an otherwise ordinary character (e.g. GNU's \b, \s, \w), meaning we may have two different valid interpretations of the same sequence. To make this easier to deal with and given that the standard calls this undefined, we should throw an error (EESCAPE) if we run into this scenario to ease transition into a state where some escaped ordinaries are blessed with a special meaning -- it will either error out or have extended behavior, rather than have two entirely different versions of undefined behavior that leave the consumer of regex(3) guessing as to what behavior will be used or leaving them with false impressions. This change bumps the symbol version of regcomp to FBSD_1.6 and provides the old escape semantics for legacy applications, just in case one has an older application that would immediately turn into a pumpkin because of an extraneous escape that's embedded or otherwise critical to its operation. This is the final piece needed before enhancing libregex with GNU extensions and flipping the switch on bsdgrep.
