| | | | | | | | | | | | | | | | | | | | | | | | | | | | | setenv(3) by tracking the size of the memory allocated instead of using strlen() on the current value. Convert all calls to POSIX from historic BSD API: - unsetenv returns an int. - putenv takes a char * instead of const char *. - putenv no longer makes a copy of the input string. - errno is set appropriately for POSIX. Exceptions involve bad environ variable and internal initialization code. These both set errno to EFAULT. Several patches to base utilities to handle the POSIX changes from Andrey Chernov's previous commit. A few I re-wrote to use setenv() instead of putenv(). New regression module for tools/regression/environ to test these functions. It also can be used to test the performance. Bump __FreeBSD_version to 700050 due to API change.

Further, when we set the BLOCKSIZE environment variable, we use "1k" instead of "1024", making the header display incorrectly. To quote the specification: "When both the -k and -P options are specified, the following header line shall be written (in the POSIX locale): "Filesystem 1024-blocks Used Available Capacity Mounted on\n" - If -P has been specified, check to make sure that -k has not already been specified, if so, simply break instead of clobbering the previous blocksize - Use 1024 instead of 1k to make the header POSIX compliant Reported by: Andriy Gapon Discussed with: bde, ru MFC after: 1 week Notes: svn path=/head/; revision=162483

The reason for this is that df -t will call statfs(2) on the pathname supplied by getfsstat(2). This is done to refresh the file system statistics in the event that a previous file system had a long delay in providing its stats. This change affects the df utility in the following ways: o Teach df has to deal with statfs(2) failing. If statfs(2) fails, fall back on the possibly stale stats provided by the initial call to getfsstat(2). o Print a warning that the fs stats could possibly be stale o Modify the man page and document this new behavior as a bug.

There are places where (void *) pointers are not valid, such as for function pointers, but in the special case of (void *)0, agreement settles on it being OK. Most of the fixes were NULL where an integer zero was needed; many of the fixes were NULL where ascii <nul> ('\0') was needed, and a few were just "other".

You should build and boot a new kernel BEFORE doing a `make world' as the new kernel will know about binaries using the old statfs structure, but an old kernel will not know about the new system calls that support the new statfs structure. Running an old kernel after a `make world' will cause programs such as `df' that do a statfs system call to fail with a bad system call.

* Fixed exit code in previous commit. "var++" to set a flag to nonzeroBruce Evans2003-06-031-5/+9
| | | | | | | | | | | | | | | | | | | is a style bug at best. When the variable isn't a flag, it potentially overflows after a large number of settings. Here the number of settings is limited by ARG_MAX, but the variable is the exit code so it became bogus after the second setting and effectively overflowed to 0 after approx. 128 settings. Fixed some style bugs involving comments in and near previous commit. Clarification of previous commit message: df -t didn't give undefined behaviour, and the behaviour used to conform perfectly with the man page, since the buggy behaviour is documented in the BUGS section. -t just worked when no files or file systems were specified, and was just ignored if a file or file system was specified.

| | | | | | | | | | | | | | | | | | | | | | | | | | - Make getvfsbyname() take a struct xvfsconf *. - Convert several consumers of getvfsbyname() to use struct xvfsconf. - Correct the getvfsbyname.3 manpage. - Create a new vfs.conflist sysctl to dump all the struct xvfsconf in the kernel, and rewrite getvfsbyname() to use this instead of the weird existing API. - Convert some {set,get,end}vfsent() consumers to use the new vfs.conflist sysctl. - Convert a vfsload() call in nfsiod.c to kldload() and remove the useless vfsisloadable() and endvfsent() calls. - Add a warning printf() in vfs_sysctl() to tell people they are using an old userland. After these changes, it's possible to modify struct vfsconf without breaking the binary compatibility. Please note that these changes don't break this compatibility either. When bp will have updated mount_smbfs(8) with the patch I sent him, there will be no more consumers of the {set,get,end}vfsent(), vfsisloadable() and vfsload() API, and I will promptly delete it.
