* Make the implementation and documentation agree. Specifically:Dag-Erling Smørgrav1999-01-062-6/+11
| | | | | | | | | | - document that sysctl() and sysctlbyname() return 0 on success - if the provided buffer is too small, set errno to ENOMEM and return -1 instead of returning ENOMEM. Notes: svn path=/head/; revision=42353
* Ignore the fs_spec entry for "/" in /etc/fstab if the device whichBruce Evans1999-01-011-0/+29
| | | | | | | | | | | is actually mounted on "/" can be determined using statfs() and is in /dev. This fixes fsck operating on the wrong device when the fs_spec entry is only an alias. The aliased case became more dangerous when the ROOTSLICE_HUNT hack was committed in mount(8). ROOTSLICE_HUNT may be unnecessary now. Notes: svn path=/head/; revision=42232

* A feeble attempt at kld compatability. The mount_* programs assume thatPeter Wemm1998-11-031-1/+10
| | | | | | | | | | | | | | they cannot mount a filesystem that they cannot see in getvfsbyname(). Part 1 of this is a hack, make vfsisloadable() always return true - the ultimate decider of whether it's loadable or not is kldload() or mount(). Part 2 of this is to have vfsload() call kldload(2) and return success if it works. This means that we will use a viable kld module in preference to an LKM! Ultimately, the thing to do is remove the hacks to do a vfsload in all the mount_* commands and let the kernel do it by itself in mount(2). Notes: svn path=/head/; revision=40863

* Avoid the need for calling functions that malloc after a vfork().Peter Wemm1998-10-111-2/+10
| | | | Notes: svn path=/head/; revision=40219
* vfork -> fork. The child calls execl() which calls malloc(), soBruce Evans1998-10-101-1/+1
| | | | | | | | | | | | vfork() can't be used. We could use alloca() in execl() so that it can be called between vfork() and execve(), but a "portable" popen() shouldn't depend on this. Calling execle() instead of execl() should be fairly safe, since execle() is supposed to be callable from signal handlers and signal handlers can't call malloc(). However, execle() is broken.

* Replace memory leaking instances of realloc with non-leaking reallocf.Warner Losh1998-09-169-19/+19
| | | | | | | | | | | | | | In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...
