MEMSETOOBSEL is completely unused and useless. Remove the definition.
Note: it's probably best not to use this ioctl number in the future for
MTD, since that may cause conflicts between old kernels and new user
software (or new kernels and old user software).Artem: leave a comment about MEMSETOOBSEL.

Lots (nearly all) mtd drivers contain nearly the similar code that
calls parse_mtd_partitions, provides some platform-default values, if
parsing fails, and registers mtd device.This is an aim to provide single implementation of this scenario:

According to our new prefix rules, we should rename NAND_CREATE_EMPTY_BBT
with a NAND_BBT prefix, i.e., NAND_BBT_CREATE_EMPTY.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
The NAND_CREATE_EMPTY_BBT flag was added by commit:
453281a973c10bce941b240d1c654d536623b16b
mtd: nand: introduce NAND_CREATE_EMPTY_BBT
This flag is not used within the kernel and not explained well, so I
took the liberty to edit its comments.Also, this is a BBT-related flag (and closely tied with NAND_BBT_CREATE)
so I'm moving it to bbm.h next to NAND_BBT_CREATE, thus requiring that
we use the flag in nand_chip.bbt_options, *not* in nand_chip.options.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
Recall the recently added prefix requirements:
* "NAND_" for flags in nand.h, used in nand_chip.options
* "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options
or in nand_bbt_descr.optionsThus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH.
Again, this flag is found in bbm.h and so should NOT be used in the
"nand_chip.options" field.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
This patch works with the following three flags from two headers (nand.h
and bbm.h):
(1) NAND_USE_FLASH_BBT (nand.h)
(2) NAND_USE_FLASH_BBT_NO_OOB (nand.h)
(3) NAND_BBT_NO_OOB (bbm.h)These flags are all related and interdependent, yet they were in
different headers. Flag (2) is simply the combination of (1) and (3) and
can be eliminated.This patch accomplishes the following:
* eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2))
* move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.hIt's important to note that because (1) and (3) are now both found in
bbm.h, they should NOT be used in the "nand_chip.options" field.I removed a small section from the mtdnand DocBook because it referes to
NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.Signed-off-by: Brian Norris
Signed-off-by: Artem Bityutskiy -
This patch handles the problems we've been having with using conflicting
flags from nand.h and bbm.h in the same nand_chip.options field. We
should try to separate these two spaces a little more clearly, and so I
have added a bbt_options field to nand_chip.Important notes about nand_chip fields:
* bbt_options field should contain ONLY flags from bbm.h. They should be
able to pass safely to a nand_bbt_descr data structure.
- BBT option flags start with the "NAND_BBT_" prefix.
* options field should contian ONLY flags from nand.h. Ideally, they
should not be involved in any BBT related options.
- NAND chip option flags start with the "NAND_" prefix.
* Every flag should have a nice comment explaining what the flag is. While
this is not yet the case on all existing flags, please be sure to write
one for new flags. Even better, you can help document the code better
yourself!Please try to follow these conventions to make everyone's lives easier.
Among the flags that are being moved to the new bbt_options field
throughout various drivers, etc. are:
* NAND_BBT_SCANLASTPAGE
* NAND_BBT_SCAN2NDPAGE
and there will be more to come.Signed-off-by: Brian Norris

This patch reverts most of:
commit 58373ff0afff4cc8ac40608872995f4d87eb72ec
mtd: nand: more BB Detection refactoring and dynamic scan optionsAccording to the discussion at:
http://lists.infradead.org/pipermail/linux-mtd/2011-May/035696.html
the NAND_BBT_SCANBYTE1AND6 flag, although technically valid, can break
some existing ECC layouts that use the 6th byte in the OOB for ECC data.
Furthermore, we apparently do not need to scan both bytes 1 and 6 in
the OOB region of the devices under consideration; instead, we only need
to scan one or the other.Thus, the NAND_BBT_SCANBYTE1AND6 flag is at best unnecessary and at
worst a regression.Signed-off-by: Brian Norris

The patch http://lkml.org/lkml/2003/7/13/226 introduced an RLIMIT_NPROC
check in set_user() to check for NPROC exceeding via setuid() and
similar functions.Before the check there was a possibility to greatly exceed the allowed
number of processes by an unprivileged user if the program relied on
rlimit only. But the check created new security threat: many poorly
written programs simply don't check setuid() return code and believe it
cannot fail if executed with root privileges. So, the check is removed
in this patch because of too often privilege escalations related to
buggy programs.The NPROC can still be enforced in the common code flow of daemons
spawning user processes. Most of daemons do fork()+setuid()+execve().
The check introduced in execve() (1) enforces the same limit as in
setuid() and (2) doesn't create similar security issues.Neil Brown suggested to track what specific process has exceeded the
limit by setting PF_NPROC_EXCEEDED process flag. With the change only
this process would fail on execve(), and other processes' execve()
behaviour is not changed.Solar Designer suggested to re-check whether NPROC limit is still
exceeded at the moment of execve(). If the process was sleeping for
days between set*uid() and execve(), and the NPROC counter step down
under the limit, the defered execve() failure because NPROC limit was
exceeded days ago would be unexpected. If the limit is not exceeded
anymore, we clear the flag on successful calls to execve() and fork().The flag is also cleared on successful calls to set_user() as the limit
was exceeded for the previous user, not the current one.Similar check was introduced in -ow patches (without the process flag).
v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().

Currently userland will barf when including linux/netlink.h unless it
precisely includes sys/socket.h first. The issue is where the
definition of "sa_family_t" comes from.We've been back and forth on how to fix this issue in the past, see:
http://thread.gmane.org/gmane.linux.debian.devel.bugs.general/622621
http://thread.gmane.org/gmane.linux.network/143380Ben Hutchings suggested we take a hint from how we handle the
sockaddr_storage type. First we define a "__kernel_sa_family_t"
to linux/socket.h that is always defined.Then if __KERNEL__ is defined, we also define "sa_family_t" as
equal to "__kernel_sa_family_t".Then in places like linux/netlink.h we use __kernel_sa_family_t
