* | fs: allocate FILE table dynamicallySascha Hauer2013-03-141-4/+7
|/ | | | | | | | | Some systems are runnignfrom a very limited SRAM, but have a huge malloc space in SDRAM. The bss normally is in SRAM, so we should avoid having big structures there. The FILE table is 5120 bytes big, so allocate it dynamically instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: add pread and pwrite functionsAlexander Aring2013-02-201-14/+74
| | | | | | | | | | | | | | | Add pread and pwrite functions. Split read and write functions to save some space. The functions pread and pwrite saves and sets the file position to a given offset and restore them afterwards. This also makes the nandtest command use these function which is necessary to not break compilation for the nandtest command.

| * | tftp: reset timer on progressSascha Hauer2013-01-201-10/+11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | When during tftp receive operation a ACK packet can't successfully be sent the timer was resetted directly after send resulting in a deadlock. This patch changes the timer reset operation in a way that it is only resetted when the actually is progress, namely in the TFTP_ACK/TFTP_DATA pathes in the tftp handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_add_child is a very unsafe function.

* fs: fix standard zero, full devicesSascha Hauer2012-07-042-5/+6
| | | | | | | | | | | | | | | | The standard devices are currently broken since they have the size ~0. As now files use loff_t as file size which is a signed type the read implementation gets confused and now returns -1. The current implementation also has the (somewhat theorical) problem that we do not have real streaming devices, so /dev/zero went out of zeroes after reading 4GB (or now LLONG_MAX). This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new file size flag FILE_SIZE_STREAM which makes it possible to create real stream devices instead.

| | | | | | | | | | | | | | | | | | | | Storing the size instead of the resource end in struct resource was a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously leads to problems. 'end' on the other hand will never exceed UINT[32|64]_MAX. Also this way we can express a iomem region covering the whole address space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
