svn commit: r236045 - in head/sys/i386: i386 include
Author: alc
Date: Sat May 26 06:10:25 2012
New Revision: 236045
URL: http://svn.freebsd.org/changeset/base/236045
Log:
Rename pmap_collect() to pmap_pv_reclaim() and rewrite it such that it no
longer uses the active and inactive paging queues. Instead, the pmap now
maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses
this list to select pv entries for reclamation.
Note: The old pmap_collect() tried to avoid reclaiming mappings for pages
that have either a hold_count or a busy field that is non-zero. However,
this isn't necessary for correctness, and the locking in pmap_collect() was
insufficient to guarantee that such mappings weren't reclaimed. The new
pmap_pv_reclaim() doesn't even try.

svn commit: r236061 - head/sys/dev/sym
Author: marius
Date: Sat May 26 08:03:42 2012
New Revision: 236061
URL: http://svn.freebsd.org/changeset/base/236061
Log:
- When creating the DMA tag for user data, don't ask for more segments
than required for handling MAXPHYS and report the resulting maximum
I/O size to CAM instead of implicitly limiting it to DFLTPHYS.
- Move the variables of sym_action2() out of nested scope as required
by style(9) and remove extraneous curly braces.
- Replace a magic value for PCIR_COMMAND with the appropriate macro.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
Tested with a HBA donated by wilko.

Remove use of non-ISO-C integer types from system call tables.
These files already use ISO-C-style integer types, so make them less
inconsistent by preferring the standard types.
These should actually be Linux types l_foo_t. ISO-C-style integer types
seem to have only been used for a couple of uintptr_t's, and these uses
are more than just style bugs on amd64 since uintptr_t is for the host
(64 bits on amd64) while the target uintptr_t is only 32 bits. There
are also a few misuses of the abominable caddr_t instead of l_caddr_t,
so syscalls that don't even take a caddr_t. Otherwise, Linux types
are used a lot to avoid size mismatches.

argp and envp aren't uintany_t * in either Linux or FreeBSD. They start as
char * const *. There is no Linux type for an indirect char *, and one
was hacked up here by pretending that char * is u_int32_t (it is actually
just 32 bits). Using l_caddr_t seems to be the best hack available (since
by abusing l_caddr_t, we know that it is actually char *).
The `const' in the type for argp and envp is further from being handled
correctly. Most or all syscall.master's just type-pun it away. Similarly
for const char *path.
All the non-indirect char *s for pathnames and other things seem to be
completely wrong on amd64 too. These pointers start as 32 bits, and it
takes more than a bad type pun to turn then into kernel 64-bit pointers.
The magic for this seems to be:
- all args are converted to 64 bits (by zero-extension?) at a low level
- the args struct for a pathname is
[left padding]; char *; [right padding];
Since the char * is misdeclared, the explicit padding is null, but the
layout of the args struct is correct because the wrong arg type in it
supplies equivalent padding (extra 32 bits on the right).
- the char * in the args struct is not actually a char *, and is unusable
directly in the kernel. However, it is only used in copyin() and
copyout(), where it becomes a user address and works correctly. (An
older bug in this that the user address for copy*() is declared as
void *. void * means a kernel pointer. The type of a user
address should be more like vm_offset_t, but even that needs logical
translation for linux32).
The same mechanism presumably avoids problems when raw caddr_t is used
instead of l_caddr_t, and when uintptr_t is used instead of l_uintptr_t.
12 AUE_CHDIR STD { int linux_chdir(char *path); }
13 AUE_NULLSTD { int linux_time(l_time_t *tm); }
Example of a correct use of a linux type. Again, the first-level pointer
is handled by the above magic, but for the second level we need an l_foo_t
to describe its size correctly.
14 AUE_MKNOD STD { int linux_mknod(char *path, l_int mode, \
Broken except in the KR case, but amd64 is too new to pretend to support
KR. Bug for bug compatible with mknod() and some other syscalls in
kern/syscalls.master. mknod() takes an arg of type mode_t, not one of
type int. l_mode_t exists so that the above can be declared correctly,
and is already used for linux_chmod() and linux_chmodat(). OTOH, int for
the mode arg is correct for open(), since open() is variadic at a level
before the syscall, so its mode_t arg gets promoted to int. Similarly,
if mknod() is compiled by a KR compiler, or by a STDC compiler with no
prototype in scope, then its mode_t arg gets promoted to int (but for
the STDC case, the behaviour is then undefined once mknod() is reached).
Normally this doesn't cause any problems, but it is easy to declare
things correctly.

Remove use of non-ISO-C integer types from system call tables.
These files already use ISO-C-style integer types, so make them less

These should actually be Linux types l_foo_t. ISO-C-style integer types
seem to have only been used for a couple of uintptr_t's, and these uses
are more than just style bugs on amd64 since uintptr_t is for the host
(64 bits on amd64) while the target uintptr_t is only 32 bits. There
are also a few misuses of the abominable caddr_t instead of l_caddr_t,
so syscalls that don't even take a caddr_t. Otherwise, Linux types
are used a lot to avoid size mismatches.

argp and envp aren't uintany_t * in either Linux or FreeBSD. They start as
char * const *. There is no Linux type for an indirect char *, and one
was hacked up here by pretending that char * is u_int32_t (it is actually
just 32 bits). Using l_caddr_t seems to be the best hack available (since
by abusing l_caddr_t, we know that it is actually char *).
The `const' in the type for argp and envp is further from being handled
correctly. Most or all syscall.master's just type-pun it away. Similarly
for const char *path.
All the non-indirect char *s for pathnames and other things seem to be
completely wrong on amd64 too. These pointers start as 32 bits, and it
takes more than a bad type pun to turn then into kernel 64-bit pointers.
The magic for this seems to be:
- all args are converted to 64 bits (by zero-extension?) at a low level
The 'low level' AKA magic happens in several *_fetch_syscall_args()
functions. For both linux32 and freebsd32, the magic code automatically
zero-extends the arguments into 64bit entities. Linux passes args in
registers, while FreeBSD uses words on stack.
The types in the syscalls.master prototype should be in fact selected
to fit the in-kernel prototypes for the functions implementing the syscalls,
esp. for NOPROTO cases, and not to the low-level layout of the syscall
entry data.
- the args struct for a pathname is
[left padding]; char *; [right padding];
Since the char * is misdeclared, the explicit padding is null, but the
layout of the args struct is correct because the wrong arg type in it
supplies equivalent padding (extra 32 bits on the right).
The arg struct layout is irrelevant, since fetch_syscall_args() functions
perform the needed translation from process ABI to kernel ABI.
I think that the padding could be completely eliminated for translated
ABI, but since it is easier to reuse makesyscalls.sh instead of creating
ABI-specific script, and since there is quite non-trivial count of NOPROTO
declarations that just match the native-ABI syscall handlers, it is better
not to start that.
- the char * in the args struct is not actually a char *, and is unusable
directly in the kernel. However, it is only used in copyin() and
copyout(), where it becomes a user address and works correctly. (An
older bug in this that the user address for copy*() is declared as
void *. void * means a kernel pointer. The type of a user
address should be more like vm_offset_t, but even that needs logical
translation for linux32).
It is char *, but in different address space. Linux-style type qualifiers
like __usermode would be appropriate there (remember far/near ?), but
we do not have static checkers that do understand the difference.
The same mechanism presumably avoids problems when raw caddr_t is used
instead of l_caddr_t, and when uintptr_t is used instead of l_uintptr_t.

13 AUE_NULLSTD { int linux_time(l_time_t *tm); }
Example of a correct use of a linux type. Again, the first-level pointer
is handled by the above magic, but for the second level we need an l_foo_t
to describe its size correctly.

argp and envp aren't uintany_t * in either Linux or FreeBSD. They start as
char * const *. There is no Linux type for an indirect char *, and one
was hacked up here by pretending that char * is u_int32_t (it is actually
just 32 bits). Using l_caddr_t seems to be the best hack available (since
by abusing l_caddr_t, we know that it is actually char *).
The `const' in the type for argp and envp is further from being handled
correctly. Most or all syscall.master's just type-pun it away. Similarly
for const char *path.
All the non-indirect char *s for pathnames and other things seem to be
completely wrong on amd64 too. These pointers start as 32 bits, and it
takes more than a bad type pun to turn then into kernel 64-bit pointers.
The magic for this seems to be:
- all args are converted to 64 bits (by zero-extension?) at a low level
...
The 'low level' AKA magic happens in several *_fetch_syscall_args()
functions. For both linux32 and freebsd32, the magic code automatically
zero-extends the arguments into 64bit entities. Linux passes args in
registers, while FreeBSD uses words on stack.
Actually, the amd64 linux_fetch32_fetch_syscall_args() just copies from
64-bit registers frame-tf_r* to 64-bit sa-args[*]. I can't see how
this gives anything except garbage in the top bits. Is there magic in
the switch to 64-bit mode that sets the top bits? Anyway, sign extension
would give garbage for unsigned args, and zero-extension would give
garbage for negative signed args.
The amd64 ia32_fetch_syscall_args() is quite different. Now the args
stack as 32 bits on the stack, so normal C accesses naturally extend
them when assigning them to 64-bit memory sa-args[*]. The stack is
in user space, so normal C accesses are unavailable at first. sa-code
is read using fuword32(), which gives zero-extension. Then the stack
is copied in and normal C accesses become available. Finally, all
args are copied from 32-bit args[i] to 64-bit sa-args[i]. args[i]
is u_int32_t, so this indeed gives zero-extension. But args[i] is
signed (int64_t), since it is register_t which is bogusly signed.
So for negative args, overflow occurs when int32_t accessed as u_int32_t
via the type pun in the declaration of args[]. There is no further
overflow when the result is assigned to sa-args[i], but the result
is wrong (no longer negative). It takes further magic to undo this.
BTW, struct syscall_args has bad names and formatting. It is missing
indentation and sa_prefixes for all its members. These bugs are missing
for the 64-bit register side of the copy (struct trapframe).
The types in the syscalls.master prototype should be in fact selected
to fit the in-kernel prototypes for the functions implementing the syscalls,
No, they have to match the types actually passed so as to ignore any
garbage bits created by previous magic steps. The lower levels cannot
do a correct conversion since they don't have access to the type info
generated from syscalls.master, and they shouldn't do a correct conversion
since this is easier to do later -- only the functions implementing the
syscalls can do it easily. The type info is mostly encoded in syscall
args structs for the individual functions, in a way that the conversions
only need to access fields in the structs to do the conversions (this
only works for simple conversions but handles ignoring any leading and
trailing bits up to reasonably boundaries, since this is needed for
endianness handling).
esp. for NOPROTO cases, and not to the low-level layout of the syscall
entry data.
Of course the layout must match the one actually used by the function
implementing the syscall. For NOPROTO cases, this is given
