1999-08-13Better fix for fdesc/procfs panic.Constantine Sapuntzakis
1999-08-13in *_readdir(), constrain uio_offset to make sure it is right; cstone@pobox.comTheo de Raadt
1999-05-31New struct statfs with mount options. NOTE: this replaces statfs(2),Todd C. Miller
fstatfs(2), and getfsstat(2) so you will need to build a new kernel before doing a "make build" or you will get "unimplemented syscall" errors. The new struct statfs has the following featuires: o Has a u_int32_t flags field--now softdep can have a real flag. o Uses u_int32_t instead of longs (nicer on the alpha). Note: the man page used to lie about setting invalid/unused fields to -1. SunOS does that but our code never has. o Gets rid of f_type completely. It hasn't been used since NetBSD 0.9 and having it there but always 0 is confusing. It is conceivable that this may cause some old code to not compile but that is better than silently breaking. o Adds a mount_info union that contains the FSTYPE_args struct. This means that "mount" can now tell you all the options a filesystem was mounted with. This is especially nice for NFS. Other changes: o The linux statfs emulation didn't convert between BSD fs names and linux f_type numbers. Now it does, since the BSD f_type number is useless to linux apps (and has been removed anyway) o FreeBSD's struct statfs is different from our (both old and new) and thus needs conversion. Previously, the OpenBSD syscalls were used without any real translation. o mount(8) will now show extra info when invoked with no arguments. However, to see *everything* you need to use the -v (verbose) flag.
1999-04-28zap the newhashinit hack.Artur Grabowski
Add an extra flag to hashinit telling if it should wait in malloc. update all calls to hashinit.

1998-12-24in kernfs_statfs set f_flags to 0Todd C. Miller
1998-11-13When vclean calls VOP_LOCK (dead_lock in this case) it has already setArtur Grabowski
the VXLOCK flag. Calling chkvnlock in that case causes a deadlock. XXX note that only vclean passes LK_DRAIN to VOP_LOCK and don't call chkvnlock XXX in that case.
1998-08-30OK, this is another fix for the infamous i386 "PTDI panic". This fix is thePer Fogelstrom
same as is used in 'vslock()'. The situation when this occurs is when a process tries to read or write to another process vm space and the _segment_ referenced have not yet been mapped. A certain way of crashing a system is to debug a program larger than 4 Mb (yes, those critters exist!). Set a break in an address above 4 Mb and pmap_enter panics because it can't fault in a new ptd page since it is not the process itself that calls pmap_enter. This is a fix, not a solution, but at least a user can't crash the kernel.

1998-08-06Fix the typos that prevented umap from working. They, of course, leadConstantine Sapuntzakis
to the obvious question: don't you run this stuff before you check it in? Sadly, the answer was no in this case. But, I'm trying to learn. Slowly, painfully....
1998-08-06Don't pass vclean related stuff to the lower vnode. It makes it very unhappy.Constantine Sapuntzakis
1998-08-06Rename vop_revoke, vn_bwrite, vop_noislocked, vop_nolock, vop_nounlockConstantine Sapuntzakis
to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked, vop_generic_lock and vop_generic_unlock. Create vop_generic_abortop and propogate change to all file systems. Fix PR/371. Get rid of locking in NULLFS (should be mostly unnecessary now except for forced unmounts).
1998-07-13Fix locking discipline snafu with UNIONFS. Thanks to Don Schmid ↵Constantine Sapuntzakis
(yensid@imsa.edu) for the original fix and Todd Miller.

1997-09-11Fix {KERNFS,NULLFS,UMAPFS,UNION}_DIAGNOSTIC kernel compilation errors.Todd C. Miller
From Alan Barrett <apb@iafrica.com> with some changes.
1997-08-29From NetBSD (thorpej):Todd C. Miller
Fix a reversed argument which caused procfs_checkioperm() to always return OK". Add a few comments to avoid further confusion.
1997-08-161) pfs_mode should be mode_t, not u_shortTodd C. Miller
2) Fix procfs security hole. This is basically the NetBSD fix (which is based in part on Sean Eric Fagan's FreeBSD fix) with a few minor changes. The change creates as function, procfs_checkioperm(), that has check numbers 3 and 4 from sys_ptrace(). 3) Make procfs_control() use procfs_checkioperm() as well (it already had the same basic checks but some of them were incorrect). 4) Minor stylistic cleanups, including the use of the SET/CLR/ISSET macros to aid general grokability.
1997-08-01From NetBSD (mycroft):Todd C. Miller
Eliminate bogus uses of V{READ,WRITE,EXEC}. Use S_I[RWX]{USR,GRP,OTH} where appropriate.

Vic Able: > While <miscfs/kernfs/kernfs.h> has a kernfs_node, it depends > on a structure that's defined in <miscfs/kernfs/kernfs_vnops.c>. > Oops! That's not very social. :-) [I built a new kernel fine, but don't have time to run "make build" it is my intuition that this will not have any bad effects, but I didn't test. Just back it out if it hurts you and I'll try again.]
1997-04-10Don't use gcc builtin __builtin_return_address(frameno) onTodd C. Miller
