* quota: Add support for ->get_nextdqblk() for VFS quotaJan Kara2016-02-095-0/+47
| | | | | | | | Add infrastructure for supporting get_nextdqblk() callback for VFS quotas. Translate the operation into a callback to appropriate filesystem and consequently to quota format callback. Signed-off-by: Jan Kara <jack@suse.cz>
* udf: Merge linux specific translation into CS0 conversion functionAndrew Gabbasov2016-02-091-128/+152
| | | | | | | | | | | | | | | | Current implementation of udf_translate_to_linux function does not support multi-bytes characters at all: it counts bytes while calculating extension length, when inserting CRC inside the name it doesn't take into account inter-character boundaries and can break into the middle of the character. The most efficient way to properly support multi-bytes characters is merging of translation operations directly into conversion function. This can help to avoid extra passes along the string or parsing the multi-bytes character back into unicode to find out it's length.

* udf: Remove struct ustr as non-needed intermediate storageAndrew Gabbasov2016-02-093-134/+61
| | | | | | | | | | | | | | | | | | | | Although 'struct ustr' tries to structurize the data by combining the string and its length, it doesn't actually make much benefit, since it saves only one parameter, but introduces an extra copying of the whole buffer, serving as an intermediate storage. It looks quite inefficient and not actually needed. This commit gets rid of the struct ustr by changing the parameters of some functions appropriately. Also, it removes using 'dstring' type, since it doesn't make much sense too. Just using the occasion, add a 'const' qualifier to udf_get_filename to make consistent parameters sets.

* udf: Use separate buffer for copying split namesJan Kara2016-02-092-4/+22
| | | | | | | | | | | | | Code in udf_find_entry() and udf_readdir() used the same buffer for storing filename that was split among blocks and for the resulting filename in utf8. This worked because udf_get_filename() first internally copied the name into a different buffer and only then performed a conversion into the destination buffer. However we want to get rid of intermediate buffers so use separate buffer for converted name and name split between blocks so that we don't have the same source and destination buffer when converting split names.

* udf: Adjust UDF_NAME_LEN to better reflect actual restrictionsAndrew Gabbasov2016-02-094-12/+12
| | | | | | | | | | | | | | | | | Actual name length restriction is 254 bytes, this is used in 'ustr' structure, and this is what fits into UDF File Ident structures. And in most cases the constant is used as UDF_NAME_LEN-2. So, it's better to just modify the constant to make it closer to reality. Also, in some cases it's useful to have a separate constant for the maximum length of file name field in CS0 encoding in UDF File Ident structures. Also, remove the unused UDF_PATH_LEN constant.

* udf: Join functions for UTF8 and NLS conversionsAndrew Gabbasov2016-02-091-188/+90
| | | | | | | | | | | | | | There is no much sense to have separate functions for UTF8 and NLS conversions, since UTF8 encoding is actually the special case of NLS. However, although UTF8 is also supported by general NLS framework, it would be good to have separate UTF8 character conversion functions (char2uni and uni2char) locally in UDF code, so that they could be used even if NLS support is not enabled in the kernel configuration.

* udf: Parameterize output length in udf_put_filenameAndrew Gabbasov2016-02-093-11/+13
| | | | | | | | | | Make the desired output length a parameter rather than have it hard-coded to UDF_NAME_LEN. Although all call sites still have this length the same, this parameterization will make the function more universal and also consistent with udf_get_filename.

| * xfs: Split default quota limits by quota typeCarlos Maiolino2016-02-085-42/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Default quotas are globally set due historical reasons. IRIX only supported user and project quotas, and default quota was only applied to user quotas. In Linux, when a default quota is set, all different quota types inherits the same default value. An user with a quota limit larger than the default quota value, will still be limited to the default value because the group quotas also inherits the default quotas. Unless the group which the user belongs to have a custom quota limit set. This patch aims to split the default quota value by quota type. Allowing each quota type having different default values. Default time limits are still set globally. XFS does not set a per-user/group timer, but a single global timer. For changing this behavior, some changes should be made in user-space tools another bugs being fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Factor xfs_seek_hole_data into an unlocked helper which takes an xfs inode rather than a file for internal use. Also allow specification of "end" - the vfs lseek interface is defined such that any offset past eof/i_size shall return -ENXIO, but we will use this for quota code which does not maintain i_size, and we want to be able to SEEK_DATA past i_size as well. So the lseek path can send in i_size, and the quota code can determine its own ending offset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Quota IDs are unsigned, and so we can pass in values up to 2^32-1. But if we try to initialize a block containing values over MAX_INT, curid will overflow and assert. curid holds a quota ID, so give it the proper xfs_dqid_t type (and remove the now-impossible ASSERT).

| * quota: add new quotactl Q_GETNEXTQUOTAEric Sandeen2016-02-082-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Q_GETNEXTQUOTA is exactly like Q_GETQUOTA, except that it will return quota information for the id equal to or greater than the id requested. In other words, if the requested id has no quota, the command will return quota information for the next higher id which does have a quota set. If no higher id has an active quota, -ESRCH is returned. This allows filesystems to do efficient iteration in kernelspace, much like extN filesystems do in userspace when asked to report all active quotas. This does require a new data structure for userspace, as the current structure does not include an ID for the returned quota information. Today, Ext4 with a hidden quota inode requires getpwent-style iterations, and for systems which have i.e. LDAP backends, this can be very slow, or even impossible if iteration is not allowed in the configuration.

Quite a bit of the changes on OMAP were due to fixes to no longer write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also other fixes.

Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.

We had several places writing to rodata, which is bad. The fix in most cases is to load the value from data section using a pointer. Let's also enable ARM_KERNMEM_PERMS so DEBUG_RODATA gets selected by default. And while testing things, I also added few more loadable driver modules to the defconfig that I seem to need quite often. - Fix a long standing omap5 RTC mystery and enable RTC where we need to ensure the SoC msecure pin is high so we can write to the RTC registers. - Fix irq types for am437x - A series of minor dts fixes for sbc-am57x and cl-som-am57x - Fixes for torpedo dts to make WLAN behave and to remove a duplicate i2c rate entry This series also includes few minor changes that are not stricly fixes, but would be good to get in during the early -rc cycle: - Remove legacy mailbox platform data that is no longer needed - Add the pdata-quirks needed for the new pwm-omap-dmtimer so people can use it - Enable ti,mbox-send-noirq that's needed by wkup_m3 driver - Enable SPLIT and DWARF4 in omap2plus_defconfig as it makes the initramfs quite a bit smaller * tag 'omap-for-v4.5/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (23 commits) ARM: dts: am57xx: sbc-am57x: correct Eth PHY settings ARM: dts: am57xx: cl-som-am57x: fix CPSW EMAC pinmux ARM: dts: am57xx: sbc-am57x: fix UART3 pinmux ARM: dts: am57xx: cl-som-am57x: update SPI Flash frequency ARM: dts: am57xx: cl-som-am57x: set HOST mode for USB2 ARM: dts: am57xx: sbc-am57x: fix SB-SOM EEPROM I2C address ARM: dts: LogicPD Torpedo: Revert Duplicative Entries ARM: dts: am437x: pixcir_tangoc: use correct flags for irq types ARM: dts: am4372: fix irq type for arm twd and global timer ARM: dts: Fix wl12xx missing clocks that cause hangs ARM: OMAP: Add PWM dmtimer platform data quirks ARM: omap2plus_defconfig: Enable ARM_KERNMEM_PERMS and few loadable modules ARM: OMAP2+: Fix ppa_zero_params and ppa_por_params for rodata ARM: OMAP2+: Fix l2_inv_api_params for rodata ARM: OMAP2+: Fix save_secure_ram_context for rodata ARM: OMAP2+: Fix l2dis_3630 for rodata ARM: OMAP2+: Fix wait_dll_lock_timed for rodata ARM: OMAP2+: Remove legacy mailbox device instantiation ARM: dts: AM4372: Add ti,mbox-send-noirq to wkup_m3 mailbox ARM: dts: AM33xx: Add ti,mbox-send-noirq to wkup_m3 mailbox ...
