| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to increment the Logical Block Address in eax by the number of sectors we passed to getlinsec after every invocation, otherwise we'll start with the same sector everytime. This bug was discovered when booting an isohybrid image, which failed to boot after printing the following error, "Image checksum error, sorry..." because the isolinux.bin was bigger than 32K, and thus invoked the getlinsec loop that reads the file in chunks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a significant rewrite of the generic lookup logic inside core/fs/fs.c's searchdir function. Previously, there was a memory leak if a path involved multiple directories. After a sufficiently large number of invocations, this could be observed.

| |/ | | | | | | | | | | | | | | | | | | | | | | If opt.reset_adv is set the call to ext_read_adv() is skipped which would have initialised 'filename'. This means that a pointer containing random data from the stack is passed to ext_write_adv(). Just delete the opt.reset_adv logic since modify_adv() handles that case anyway.

* | com32: Fix a bug on history of commands.Raphael S.Carvalho2013-09-301-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | Previously, even zero-length commands would be added to the history when they shoudn't, e.g: just typing enter. For example, if you type: FOO -> (ENTER) -> (ENTER), then to get FOO from the history you would have to press the UP key twice. It also saves a bit of memory.

* | com32: Fix bugs on cmd_reverse_search (Triple fault dimension)Raphael S.Carvalho2013-09-301-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cmd_reverse_search has a bug that the variable cursor is updated even if a command wasn't found. If this happens, and the next key falls into the default case, memmove's size parameter would be a negative number. This bug can be reproduced by doing the following: On cmd_reverse_search (ctrl-r), type multiple keys at the same time. 'Enjoy' the triple fault and a screen of random colors. There is also a small bug that turns the task of using (ctrl-r) on the first command impossible. Previously, this command was discarded.

* | PXE ISR: Force polling on select hardware WORKAROUNDGene Cumm2013-09-301-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By OUI == 00:23:ae and flags == 0xdc1b, detect select hardware. On select platforms (Dell OptiPlex 760, Dell OptiPlex 960; perhaps more), the interrupt appears to go "deaf" after a few seconds. By matching MAC OUI and flags value, force polling on these select platforms. I'm not sure if there's any better data available that shallow in the core. I believe PCI IDs can be fetched with functions from other libraries and the UUID and DMI data (the most likely to be useful is SYSPRODUCT) is available in ldlinux.c32.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit prevents a race-condition on systems that have functional interrupts (observed with iPXE and select other Dell systems). Without this, the reply packet could be received by the core prior to the disconnect() call, see that it doesn't have a matching PCB (protocol control block, iirc) since the reply has a different far-end UDP port than the original request, and lwIP will discard the packet before PXELINUX can see it. net_core_sendto() instead of net_core_connect() net_core_send() net_core_disconnect() Commit message expanded with Matt Fleming's assistance Signed-off-by: Gene Cumm <gene.cumm@gmail.com>

For example, say a user reports trouble with their PXE stack but doesn't have a development environment setup to turn on the debug code themselves. With this change you can simply request that they do, debug.c32 -e pxe_call unload_pxe open_file to enable the debug in those functions. By only turning on code in specific functions we reduce the chance of disrupting the buggy behaviour and improve the signal to noise ratio for print statements. To disable debug code use the -d flag, debug.c32 -d pxe_call To use this new feature simply do, if (syslinux_debug_enabled) { debug1(); debug2(); .... } from within the function you wish to add debug code. Note that this feature is not limited to print statements - you can put any code within the conditional, such as verifying a checksum or checking for memory leaks. The plan is to leave the dynamic debug code built in for all prereleases and to turn it off for final releases. People may still want to build with all dprintf() statements enabled, and so a new symbol, DYNAMIC_DEBUG, was introduced rather than repurposing the old DEBUG, DEBUG_STDIO and DEBUG_PORT symbols.
