* Handle machine-dependent (m-d) (string) sources more automatically.Bruce Evans1997-10-163-80/+23
| | | | | | | | | | | | | | | | | | | | | | | | The names of m-d variants are now added (manually) to MDSRCS instead of to SRCS, and the names of all machine-independent (m-i) variants that can reasonably be replaced by an m-d variant are now added (manually) to MISRCS instead of to SRCS, so that a simple substitution can be used to discard the unused m-i variants. MISRCS is potentially all m-i sources, but the substitution is too simple to be fast, so MISRCS should be kept reasonably small. libc/Makefile.inc: Do the substitution. libc/i386/string/Makefile.inc: Add to MDSRCS instead of to SRCS. Add the names of all sources in this directory, but no others. libc/string/Makefile.inc Add to MISRCS instead of to SRCS. Add the names of all sources in this directory. Don't use (broken) explicit rules for special cases. Notes: svn path=/head/; revision=30481

* Remove old SIGALRM absorbing back-compat code. It wasn't working at allPeter Wemm1997-10-151-83/+1
| | | | | | | | | | | | | | | | for the entire time that it was there, so obviously nothing needs it anymore. Note, unix98/single-unix spec v2 says that usleep() returns an int rather than a void, to indicate whether the entire time period elapsed (0) or an error (eg: signal handler) interrupted it (returns -1, errno = EINTR) It is probably useful to make this change but I'll test it locally first to see if this will break userland programs [much]...

* Give up on the "try and compensate for broken programs" cruft and revertPeter Wemm1997-10-151-70/+0
| | | | | | | | | | | | | | | | back to the original single nanosleep() implementation. This is POSIX and Unix98 (aka single-unix spec v2) compliant behavior. If a program sets alarm(2) or an interval timer (setitimer(2)) without a SIGALRM handler being active, sleep(3) will no longer absorb it, and the program will get what it asked for..... :-] The original reason for this in the first place (apache) doesn't seem to need it anymore, according to Andrey.

* Correct a bug in the 'allow arbitrary number of socket descriptors' changesBill Paul1997-10-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | made to the RPC code some months ago. The value of __svc_fdsetsize is being calculated incorrectly. Logically, one would assume that __svc_fdsetsize is being used as a substitute for FD_SETSIZE, with the difference being that __svc_fdsetsize can be expanded on the fly to accomodate more descriptors if need be. There are two problems: first, __svc_fdsetsize is not initialized to 0. Second, __svc_fdsetsize is being calculated in svc.c:xprt_registere() as: __svc_fdsetsize = howmany(sock+1, NFDBITS); This is wrong. If we are adding a socket with index value 4 to the descriptor set, then __svc_fdsetsize will be 1 (since fds_bits is an unsigned long, it can support any descriptor from 0 to 31, so we only need one of them). In order for this to make sense with the rest of the code though, it should be: __svc_fdsetsize = howmany(sock+1, NFDBITS) * NFDBITS; Now if sock == 4, __svc_fdsetsize will be 32. This bug causes 2 errors to occur. First, in xprt_register(), it causes the __svc_fdset descriptor array to be freed and reallocated unnecessarily. The code checks if it needs to expand the array using the test: if (sock + 1 > __svc_fdsetsize). The very first time through, __svc_fdsetsize is 0, which is fine: an array has to be allocated the first time out. However __svc_fdsetsize is incorrectly set to 1, so on the second time through, the test (sock + 1 > __svc_fdsetsize) will still succeed, and the __svc_fdset array will be destroyed and reallocated for no reason. Second, the code in svc_run.c:svc_run() can become hopelessly confused. The svc_run() routine malloc()s its own fd_set array using the value of __svc_fdsetsize to decide how much memory to allocate. Once the xprt_register() function expands the __svc_fdset array the first time, the value for __svc_fdsetsize becomes 2, which is too small: the resulting calculation causes the code to allocate an array that's only 32 bits wide when it actually needs 64 bits. It also uses the valuse of __svc_fdsetsize when copying the contents of the __svc_fdset array into the new array. The end result is that all but the first 32 file descriptors get lost. Note: from what I can tell, this bug originated in OpenBSD and was brought over to us when the code was merged. The bug is still there in the OpenBSD source.

* Fixed searching of $PATH in execvp(). Do what sh(1) should do accordingBruce Evans1997-10-142-26/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to POSIX.2. In particular: - don't retry for ETXTBSY. This matches what sh(1) does. The retry code was broken anyway. It only slept for several seconds for the first few retries. Then it retried without sleeping. - don't abort the search for errors related to the path prefix, in particular for ENAMETOOLONG, ENOTDIR, ELOOP. This fixes PR1487. sh(1) gets this wrong in the opposite direction by never aborting the search. - don't confuse EACCES for errors related to the path prefix with EACCES for errors related to the file. sh(1) gets this wrong. - don't return a stale errno when the search terminates normally without finding anything. The errno for the last unsuccessful execve() was usually returned. This gave too much precedence to pathologies in the last component of $PATH. This bug is irrelevant for sh(1). The implementation still uses the optimization/race-inhibitor of trying to execve() things first. POSIX.2 seems to require looking at file permissions using stat(). We now use stat() after execve() if execve() fails with an ambiguous error. Trying execve() first may actually be a pessimization, since failing execve()s are fundamentally a little slower than stat(), and are significantly slower when a file is found but has unsuitable permissions or points to an unsuitable interpreter.

* Improve the innetgr() NIS+ compat kludge. We should only fail over to theBill Paul1997-10-131-18/+25
| | | | | | | | | | | | | | | 'slow' lookup if we get a YPERR_MAP (no such map in server's domain) error instead of failing over on any error. In the latter case, if the 'fast' search fails legitimately (i.e. the user or host really isn't a member of the specified netgroup) then we end up doing the 'slow' search and failing all over again. The result is still correct, but cycles are consumed for no good reason. Also removed the #ifdef CHARITABLE since the compat kludge is no longer optional. Notes: svn path=/head/; revision=30390
* NIS+ compatibility kludge. A long time ago, I set up innetgr() soBill Paul1997-10-111-0/+7
| | | | | | | | | | | | | | | | | that if searching through the special netgroup.byhost or netgroup.byuser maps didn't work, we would roll over to the 'slow' method of grovelling though the netgroup map and working out the dependencies on the fly. But I left this option hidden inside an #ifdef CHARITABLE since I didn't think I'd ever need it. Well, the Sun rpc.nisd NIS+ server in YP compat mode doesn't support the .byhost and .byuser reverse maps, so the failover is necessary in order to be compatible. *sigh* This closes PR #3891, and should be merged into RELENG_2_2.

* Call poll(2) from within the resolver but adapt to older kernels without itPeter Wemm1997-09-141-26/+68
| | | | | | | | | | | | | | | | if necessary. This removes the need to malloc large fd_set's for selecting on high fd's (larger than FD_SETSIZE at libc compile time). The syscall adaptive stuff only happens on the very first call. SIGSYS is masked, and if the call to poll fails with ENOSYS, then we use select for the life of the program. If poll does not fail with ENOSYS, then we always use poll and skip the once-off signal masking gunk. This may be overkill, but it saved my neck a few times while working on multiple different sets of kernel sources, some with poll, some without. Notes: svn path=/head/; revision=29380
