* mtd: add MEMWRITE ioctlBrian Norris2011-09-111-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new ioctl for writing both page data and OOB to flash at the same time. This ioctl is intended to be a generic interface that can replace other ioctls (MEMWRITEOOB and MEMWRITEOOB64) and cover the functionality of several other old ones, e.g., MEMWRITE can: * write autoplaced OOB instead of using ECCGETLAYOUT (deprecated) and working around the reserved areas * write raw (no ECC) OOB instead of using MTDFILEMODE to set the per-file-descriptor MTD_FILE_MODE_RAW * write raw (no ECC) data instead of using MTDFILEMODE (MTD_FILE_MODE_RAW) and using standard character device "write" This ioctl is especially useful for MLC NAND, which cannot be written twice (i.e., we cannot successfully write the page data and OOB in two separate operations). Instead, MEMWRITE can write both in a single operation. Note that this ioctl is not affected by the MTD file mode (i.e., MTD_FILE_MODE_RAW vs. MTD_FILE_MODE_NORMAL), since it receives its write mode as an input parameter.

* mtd: rename MTD_MODE_* to MTD_FILE_MODE_*Brian Norris2011-09-111-4/+4
| | | | | | | | | | | | | | | | These modes hold their state only for the life of their file descriptor, and they overlap functionality with the MTD_OPS_* modes. Particularly, MTD_MODE_RAW and MTD_OPS_RAW cover the same function: to provide raw (i.e., without ECC) access to the flash. In fact, although it may not be clear, MTD_MODE_RAW implied that operations should enable the MTD_OPS_RAW mode. Thus, we should be specific on what each mode means. This is a start, where MTD_FILE_MODE_* actually represents a "file mode," not necessarily a true global MTD mode.

* mtd: rename MTD_OOB_* to MTD_OPS_*Brian Norris2011-09-112-9/+9
| | | | | | | | | | These modes are not necessarily for OOB only. Particularly, MTD_OOB_RAW affected operations on in-band page data as well. To clarify these options and to emphasize that their effect is applied per-operation, we change the primary prefix to MTD_OPS_.

* mtd: move mtd_oob_mode_t to shared kernel/user spaceBrian Norris2011-09-112-15/+16
| | | | | | | | | | | | | We will want to use the MTD_OOB_{PLACE,AUTO,RAW} modes in user-space applications through the introduction of new ioctls, so we should make this enum a shared type.

* mtd: support reading OOB without ECCBrian Norris2011-09-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | This fixes issues with `nanddump -n' and the MEMREADOOB[64] ioctls on hardware that performs error correction when reading only OOB data. A driver for such hardware needs to know when we're doing a RAW vs. a normal write, but mtd_do_read_oob does not pass such information to the lower layers (e.g., NAND). We should pass MTD_OOB_RAW or MTD_OOB_PLACE based on the MTD file mode. For now, most drivers can get away with just setting: chip->ecc.read_oob_raw = chip->ecc.read_oob This is done by default; but for systems that behave as described above, you must supply your own replacement function. This was tested with nandsim as well as on actual SLC NAND.

* mtd: support writing OOB without ECCBrian Norris2011-09-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes issues with `nandwrite -n -o' and the MEMWRITEOOB[64] ioctls on hardware that writes ECC when writing OOB. The problem arises as follows: `nandwrite -n' can write page data to flash without applying ECC, but when used with the `-o' option, ECC is applied (incorrectly), contrary to the `--noecc' option. I found that this is the case because my hardware computes and writes ECC data to flash upon either OOB write or page write. Thus, to support a proper "no ECC" write, my driver must know when we're performing a raw OOB write vs. a normal ECC OOB write. However, MTD does not pass any raw mode information to the write_oob functions. This patch addresses the problems by: 1) Passing MTD_OOB_RAW down to lower layers, instead of just defaulting to MTD_OOB_PLACE 2) Handling MTD_OOB_RAW within the NAND layer's `nand_do_write_oob' 3) Adding a new (replaceable) function pointer in struct ecc_ctrl; this function should support writing OOB without ECC data. Current hardware often can use the same OOB write function when writing either with or without ECC This was tested with nandsim as well as on actual SLC NAND.

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.

* mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris2011-09-112-12/+9Star
| | | | | | | | | | | | | | | | | | | | | | | | | 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.h It'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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * | | ipv4: route non-local sources for raw socketJulian Anastasov2011-08-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The raw sockets can provide source address for routing but their privileges are not considered. We can provide non-local source address, make sure the FLOWI_FLAG_ANYSRC flag is set if socket has privileges for this, i.e. based on hdrincl (IP_HDRINCL) and transparent flags.

| * | | net: Make userland include of netlink.h more sane.David S. Miller2011-08-082-3/+5

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/143380 Ben 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 in user visible datastructures. Reported-by: Michel Machado <michel@digirati.com.br> Signed-off-by: David S.

* | | move RLIMIT_NPROC check from set_user() to do_execve_common()Vasiliy Kulikov2011-08-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
