xtraeme af97f2e875 Remove __P() 2005-08-30 20:08:01 +00:00
christos c107ef9edc - sprinkle const 
- avoid shadowed variables.

christos 8f3566ce61 PR/29782: Martin Husemann: procfs can not unmount when some process has its 
current directory in curproc. Fix from Pedro Martelletto:
We cannot call vgone() from procfs_inactive() if we are coming from
vclean(). that's what's probably causing the deadlock.

yamt 364ea008bb procfs_readdir: 
- return correct cookie when buffer size is small.
- simplify logic.

yamt 3cca1d9e20 procfs_readdir: fix an offset handling bug after addition of /proc/self. 2004-10-01 14:09:55 +00:00
yamt f8f70a5eb4 procfs_readdir: use a list macro. 2004-10-01 14:09:14 +00:00
jdolecek 845beacce3 add 'mounts' file for -o linux, which lists all currently mounted 
filesystems; Linux glibc statvfs() uses this to get some of mount flags,
and this file is also useful as /emul/linux/etc/mtab (via symlink)
 2004-09-20 17:53:08 +00:00
jrf bafcaa70cd Removed remaining caddr_t casts we do not need in miscfs. Recompiled 
kernel and ran for a day or so. There are still some caddr_t types in
the arguments of some calls, I will do those separately (later) as
they touch a lot more of the system.
Approved by christos@NetBSD.org.

simonb b6abb6ab1d Remove some assigned-to but otherwise unused variables. 2003-10-30 01:58:17 +00:00
darcy 566d30be44 Changes as discussed with itojun on tech-kern. I have modified the enums 
to have KFS or PFS differentiators.  Further I have wrapped the enum in
procfs in "#ifdef _KERNEL" as it is done in kernfs.

To see the discussion go to http://mail-index.NetBSD.org/tech-kern/2003/09/
and look for "Mismatched enums in include files" in the list.

Patches provided by Joel Baker in PR 22364, verified by myself.

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.
 2003-06-29 22:28:00 +00:00
thorpej a06b275edc Undo part of the ktrace/lwp changes. In particular: 
* Remove the "lwp *" argument that was added to vget().  Turns out
  that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
  and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
  above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
  just to appease the above.
 2003-06-29 18:43:21 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
 2003-06-28 14:20:43 +00:00
christos 210944c7de Add /proc/<pid>/stat for linux compat. j2sdk1.4.2 depends on it. 2003-05-28 18:03:15 +00:00
christos 11cc5eb2c6 Make symlinks for directories that point to the actual directory. 
Make symlinks to [kqueue] and [misc] for kqueue and misc fds.

jdolecek f331bb3205 do not show nodes corresponding to directory descriptors for process 
in fd/ subdirectory, nor allow lookup/open for the nodes
this fixes PR kern/21187 for good, and also avoids interesting directory
locking issues
 2003-04-17 20:50:46 +00:00
jdolecek 884bdfdbaf procfs_readdir(): in Pfd case, only show descriptors of types we want 
how to represent (vnodes, fifo, pipes); also use fd_getfile() et al

this avoids annoying EOPNOTSUPP error messages from ls -F and such
 2003-04-17 20:33:17 +00:00
jdolecek be4c900d41 procfs_lookup(): use fd_getfile() et al in Pfd case 2003-04-17 20:19:18 +00:00
jdolecek ed9a5a7448 use fd_getfile() in procfs_getfp(), and FILE_USE()/FILE_UNUSE() the 
returned file descriptor pointer appropriately
 2003-04-17 19:04:25 +00:00
jdolecek 64b598bf33 make some local arrays/variables static + const 2003-04-17 18:08:28 +00:00
jdolecek 98f212db7d use former genfs_eopnotsupp_rele() as genfs_eopnotsupp(), so that vnodes 
are vput()/vrele()d as necessary - some filesystems did use the wrong
one for some ops, and it's just safer to not take the chance

based on suggestion by Bill Studenmund

dsl b2aefec351 Remove pointless check against PID_MAX. Let pfind() do the validation. 
(The new pid allocation code may decide to allocate pids above PID_MAX.)

jrf a2d850baf8 This addresses PR kerm/19989. Thanks to hamajima@nagoya.ydc.co.jp for submitting this patch which enables /proc/uptime for linux emul. Patch reviewed by atatat@netbsd.org and tron@netbsd.org, approved by tron@netbsd.org. 2003-02-25 21:00:31 +00:00
martin d30bd703a5 Cast off_t expression to long long to match format even on 64 bit 
plattforms.

Shouldn't we introduce a PRIoff_t macro to create such format strings?

christos b5e0c9eb5b add LK_CANRECURSE in the locking of /dev/<pid>/fd/<n> and remove the curproc 
kludge. Thanks to fvdl.
 2003-01-03 13:54:22 +00:00
christos dbe6c38bc2 Implement /proc/<pid>/fd/<n>. This is work in progress. Questionable things: 
- Is it ok to convert DTYPE_PIPE to VFIFO and DTYPE_SOCKET to VSOCK?
    - XXX: Avoid locking issue in ls -Rl /proc by avoiding curproc
    - Does I/O to pipes work?
    - XXX: Are there security implications?

simonb c475865f39 Just use the "time" variable in the *_getattr functions instead of a call 
to (the potentially expensive) microtime().
 2002-08-03 04:52:44 +00:00
thorpej f1f51aa2b8 Move code shared by procfs and the kernel proper out of procfs and 
into the kernel proper (renaming functions from procfs_* to process_*).

christos 5ff60a19d9 Don't hide the real return code with EPERM. 2002-01-12 18:51:56 +00:00
chs 5a690c92a1 add a VOP_PUTPAGES method for all the filesystems that don't have pages, 
just unlock the interlock.
 2001-12-06 04:27:40 +00:00
thorpej 03efee5585 * Allow machine-dependent code to specify hooks for ptrace(2) 
(__HAVE_PTRACE_MACHDEP) and procfs (__HAVE_PROCFS_MACHDEP).
  These changes will allow platforms like x86 (XMM) and PowerPC
  (AltiVec) to export extended register sets in a sane manner.

* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
  FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
  ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
  /proc/N/xmmregs in procfs.

chs 6e2828061f procfs_bmap() should never be called, make it a "bad op". 
let procfs_mmap() use the default error method.

kleink 79283614b3 In procfs_readdir(), give /proc/# directories DT_DIR (rather than DT_REG). 2001-04-14 13:25:46 +00:00
fvdl 49b162566a Bump va_blocksize for the map files some more, so that programs with 
quite a few mappings have a chance of being handled correctly if
st_blksize is looked at.
 2001-03-30 20:25:11 +00:00
fvdl 2e64bebd3b For -o linux mounts, add some code to emulate /proc/#/maps. 
Needs NAMECACHE_ENTER_REVERSE to include filenames.

jdolecek 522f569810 make some more constant arrays 'const' 2001-02-21 21:39:52 +00:00
jdolecek d9466585b7 make filesystem vnodeop, specop, fifoop and vnodeopv_* arrays const 2001-01-22 12:17:35 +00:00
fvdl 4e000b75b2 Add a few linux-style files, only enabled when -o linux is specified 
for the mount. Currently these are /proc/cpuinfo and /proc/meminfo.
The former only does something on i386 right now.
