* Remove last remaining references to malloc/realloc and functions thatPeter Wemm1999-03-231-50/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | call them. All the execX() libc functions should be vfork() safe now. Specifically: - execlp() does the argument count-and-build into a vector from alloca (like the others) - buildargv() is no longer used (and gone). - execvp() uses alloca/strcpy rather than strdup(). - the ENOEXEC handler uses alloca rather than malloc. - a couple of free() calls removed - alloca works on the local stack and the allocations are freed on function exit (which is why buildargv wasn't useful - it's alloca() context would disappear on return). Along the way: - If alloca() fails (can it?), set errno = ENOMEM explicitly. - The ENOEXEC recovery routine that trys again with /bin/sh appeared to not be terminating the new argv[] array for /bin/sh, allowing it to walk off the end of the list. I dithered a bit about using alloca() even more as it's most commonly associated with gcc. However, standalone portable (using malloc) and machine-specific assembler alloca implementations appear to be available on just about all the architectures we're likely to want to port to. alloca will be the least of our problems if ever going to another compiler.

* Add a sysctl variable which can help stop chroot(2) escapes.Poul-Henning Kamp1999-03-231-2/+29
| | | | | | | | | | | | | | | | | | kern.chroot_allow_open_directories = 0 chroot(2) fails if there are open directories. kern.chroot_allow_open_directories = 1 (default) chroot(2) fails if there are open directories and the process is subject of a previous chroot(2). kern.chroot_allow_open_directories = anything else filedescriptors are not checked. (old behaviour). I'm very interested in reports about software which breaks when running with the default setting. Notes: svn path=/head/; revision=44973

| | | | | | | | | | | | request for it something like it. It was poorly worded and too far from both POSIX wording and normal (mal)practice by referring to sysconf(_SC_NGROUPS_MAX) instead of {NGROUPS_MAX} or NGROUPS. POSIX.1 uses curly braces to mark up "symbolic constants or limits [that may be] defined in certain headers". Since we don't document this markup, don't use it. Just use NGROUPS_MAX.

* Changed the type of quotactl()'s 4th arg from `char *' to `void *'Bruce Evans1999-03-051-1/+1
| | | | | | | | | | | | so that non-sloppy applications can call it without using disgusting casts to avoid warnings. The 4th arg is sort of varargs -- it must sometimes represent a filename, sometimes a struct pointer, and is sometimes unused. The arg type is still caddr_t in the kernel.

* Mostly remove the VM_STACK OPTION.Julian Elischer1999-01-261-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the definitions of a few items so that structures are the same whether or not the option itself is enabled. This allows people to enable and disable the option without recompilng the world. As the author says: |I ran into a problem pulling out the VM_STACK option. I was aware of this |when I first did the work, but then forgot about it. The VM_STACK stuff |has some code changes in the i386 branch. There need to be corresponding |changes in the alpha branch before it can come out completely. what is done: | |1) Pull the VM_STACK option out of the header files it appears in. This |really shouldn't affect anything that executes with or without the rest |of the VM_STACK patches. The vm_map_entry will then always have one |extra element (avail_ssize). It just won't be used if the VM_STACK |option is not turned on. | |I've also pulled the option out of vm_map.c. This shouldn't harm anything, |since the routines that are enabled as a result are not called unless |the VM_STACK option is enabled elsewhere. | |2) Add what appears to be appropriate code the the alpha branch, still |protected behind the VM_STACK switch. I don't have an alpha machine, |so we would need to get some testers with alpha machines to try it out. | |Once there is some testing, we can consider making the change permanent |for both i386 and alpha. | [..] | |Once the alpha code is adequately tested, we can pull VM_STACK out |everywhere. | Submitted by: "Richard Seaman, Jr." <dick@tar.com> Notes: svn path=/head/; revision=43209
