| * fs: tftp: don't maintain tftp dentries in dcacheAhmad Fatoum2019-08-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently a negative dentry is cached whenever a non-existing file was looked up over TFTP. Short of a barebox reset, there is no way to invalidate that dentry, so barebox retries the look up. Fix this by always reporting TFTP dentries as invalid in the d_revalidate callback.

| * | console: fix out-of-bounds read in dputc(/dev/*, ...)Ahmad Fatoum2019-09-021-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trying to output a single character via echo -a /dev/serial0-1 currently results in garbage output after the newline, because console.c's fops_write discards the buffer length and passes the buffer to (struct cdev)::puts which only handles NUL-terminated strings. Fix this by amending (struct cdev)::puts with a new nbytes parameter, which is correctly propagated. All this functions now return at most the nbytes parameter they were passed in. This fixes __console_puts, which used to count new lines twice in its return value.

| * pstore: Only capture log messagesSascha Hauer2019-07-091-60/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | With this pstore only captures barebox log messages printed with pr_* and dev_*, but no longer anything printed with printf and friends. When capturing the barebox output with pstore only the log messages are of interest, but not the ones printed with printf and certainly not the things typed interactively on the command line. These are logged currently because we register pstore as a barebox console. Instead, hook into pr_puts which only outputs the barebox log messages.

| | | | | | | | | | | | | | | | | | | | | | | | This adds UBIFS authentication support. For now, we do not do any authentication even on authenticated UBIFS images. Since this behaviour is not what the user normally expects when mounting authenticated images we only do this when the user explicitly allows it in "global.ubifs.allow_authenticated_unauthenticated". If the flag is false then we refuse mounting such an image and return -EPERM instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | fs: nfs: ensure rpc_req message is sendMarco Felsch2019-04-291-0/+11
|/ | | | | | | | | | | | | | Currently we send a rpc message without checking if the send was succesful and poll for a answer from the server. If the server didn't answer within the NFS_TIMEOUT window we send the package again. In case the package send wasn't successful we always run in that timeout. This gets even worse if the package send fails more than one time. Check if the package send was successful and resend the package if it wasn't to fix this behaviour.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FS_PSTORE_RAMOOPS_RO configuration option keeps barebox from zapping (clearing and fixing header ecc) all ramoops buffers on initialization. It also stops barebox from zapping invalid buffers. This causes issues when the console writing code tries to use the uninitialized, invalid console buffer. Therefore, allow barebox to zap invalid buffers, the kernel will do so anyway if it finds broken buffers during its initialization.

Device Tree lets us replace those shims with generic code. These bindings mirror the ramoops module parameters, with two small differences: (1) dump_oops becomes an optional "no-dump-oops" property, since ramoops sets dump_oops=1 by default. (2) mem_type=1 becomes the more self-explanatory "unbuffered" property.
