* core: Avoid initializing the cache more than onceRaphael S. Carvalho2014-04-031-0/+1
| | | | | | | | | | Most of file system drivers initialize the cache themselves. The problem is that the same cache could be again initialized later, then invalidating the previous one. This patch fixes this. Problem found while auditing the code. Signed-off-by: Raphael S. Carvalho <raphael.scarv@gmail.com>
* Add filesystem UUID to SYSAPPEND for FATSerj Kalichev2014-03-131-0/+4
| | | | | | | | | | Filesystem UUID shows the partition we boot kernel from. The kernel parameter has format like FSUUID=DA1A-0B2E. The SYSAPPEND bit is 0x40000. Now the FAT only supports FSUUID.

This conflict manifests as PXELINUX being unable to find and load files. An example dnsmasq log looks like, dnsmasq-tftp: sent /arch/boot/syslinux/lpxelinux.0 to 192.168.0.90 dnsmasq-tftp: file /arch/ldlinux.c32 not found dnsmasq-tftp: file /arch//ldlinux.c32 not found dnsmasq-tftp: file /arch//boot/isolinux/ldlinux.c32 not found dnsmasq-tftp: file /arch//isolinux/ldlinux.c32 not found dnsmasq-tftp: file /arch//boot/syslinuxldlinux.c32 not found dnsmasq-tftp: sent /arch//boot/syslinux/ldlinux.c32 to 192.168.0.90 dnsmasq-tftp: error 0 No error, file close received from 192.168.0.90 dnsmasq-tftp: failed sending /arch//boot/syslinux/ldlinux.c32 to 192.168.0.90 dnsmasq-tftp: sent /arch/boot/syslinux/archiso.cfg to 192.168.0.90 dnsmasq-tftp: sent /arch/boot/syslinux/whichsys.c32 to 192.168.0.90 dnsmasq-tftp: file /arch/libcom32.c32 not found dnsmasq-tftp: file /arch//libcom32.c32 not found dnsmasq-tftp: file /arch/libcom32.c32 not found dnsmasq-tftp: file /arch//arch//boot/syslinux/libcom32.c32 not found The last line of the log is the indication that there's a problem. Internally, Syslinux adds the location of ldlinux.c32 to PATH by querying the current working directory once ldlinux.c32 is successfully loaded. Under PXELINUX that means the initial PATH string will be, "::/arch/boot/syslinux/" The PATH parsing code doesn't know how to correctly parse the "::" string and hence, the file is searched for relative to the 210 dhcp option directory - /arch/. Implement PATH with a linked list which *greatly* simplifies the path code, and means we no longer have to parse strings backwards and forwards. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Files in the installation directory should be able to be executed (along with their dependencies) from any directory in the file hierarchy. Using the installation directory as the default value for 'PATH' is the most sensible way to do this. The PATH config directive still allows other directories to be appended to the 'PATH' variable, which is useful when there are other directories containing modules.

This patch fixes it by looking first if the argv[0] is the path to a module before looking for it at PATH. Since we're using fopen to open module files (which works for both absolute paths and paths relative to the current working directory) we no longer need to include "." in PATH and neither the code to handle it.

| * | ldlinux: Avoid initialised data memory corruptionMatt Fleming2012-03-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't realloc() 'PATH' because realloc() may just extend the malloc'd region if the adjacent region is free, as opposed to allocating a new region and then copying the data. This behaviour is fine in most circumstances but not with initialised string data, such as 'PATH'. The reason is that other string data pointers may point to characters in 'PATH' and if we modify it after realloc()'ing, we'll appear to corrupt unrelated string data. For example, the string "/" is used in chdir() and the address of that string is the last "/" in 'PATH'. If we realloc() and then append "foo" to 'PATH' the string pointer in chdir() will now point to "/foo". Initialise 'PATH' at runtime using malloc() and free() to avoid corrupting string data.

* | core: Fix ldlinux.c32 failing to load when not installed in "/"Matt Fleming2011-07-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if syslinux is installed in a directory other than "/" we will fail to load ldlinux.c32. Because we know where we were installed the simplest fix is to chdir() to the installation directory before attempting to load ldlinux.c32. This requires us to add "." to PATH so that we look in the current working directory when loading ELF modules. Changing to the install directory needs to handled differently for different file systems, which is the reason behind the new file system operation, .chdir_start(). Disk-based Syslinux variants should use generic_chdir_start() to chdir() to CurrentDirName, which is the installation path. By using this new fs operation, we can load ldlinux.c32 when we expand the "." in PATH, without having to search the entire filesystem for it. However, iso9660 file systems still require us to search some directories because it has no notion of an installation directory. Previously, changing into the install directory was handled when opening the config file, but because the config file parser is now part of the ldlinux.c32 ELF module, it needs to be done much earlier.

| | | | | | | | The 16-bit API to opendir/readdir/closedir was confused, had a memory leak, and was incompatible with Syslinux 3.x anyway. Replace it with a pure 32-bit API. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* fs: add no_next_extent() dummy functionH. Peter Anvin2010-02-281-0/+3
| | | | | | | | Add a no_next_extent() dummy function for filesystems (like iso9660) which should never end up calling next_extent (because there is only one extent...) Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* core: fs: get rid of the prev_extent memberH. Peter Anvin2010-02-281-2/+2
| | | | | | | | The prev_extent member was only ever used transiently; instead pass the new lstart in as an argument and leave the previous value of next_extent unmolested and thus can be used in-place. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* core: get rid of unmangle_name completelysyslinux-4.00-pre31H. Peter Anvin2010-02-281-2/+0
| | | | | | | | | | | | The notion of "mangle name" is now restricted to producing a canonical representation, e.g. changing \ -> / for FAT filesystems. However, the resulting mangled name is now always human-readable, so there never is any reason to unmangle a name. Get rid of not just the mangling, but of the resulting unmangled-name buffers and so on. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* core: remove unmangle_nameH. Peter Anvin2010-02-281-2/+0
| | | | | | Remove the now-obsolete unmangle_name method. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* fat: use generic_getfssec(), fix generic_getfssec(), add dprintfH. Peter Anvin2010-02-261-1/+1
| | | | | | | | | | | | | Use generic_getfssec() for the FAT filesystem. Do a bunch of calculations based on clusters rather than on sectors, so we don't have to do the same thing N times for N sectors per cluster. Fix boundary conditions in generic_getfssec(). Adjust iso9660 to match the resulting interface change. Add dprintf's to generic_getfssec() and a few other routines. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* fs: add generic getfssecH. Peter Anvin2010-02-261-2/+25
| | | | | | | | Add a generic getfssec method which operate on cached extents. This should avoid the need to each filesystem to implement its own getfssec loop. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* core: fix double free of pathbuf, constify iget filename, fix iso9660H. Peter Anvin2010-02-241-1/+1
| | | | | | | | | | Fix double free of pathbuf in searchdir(). Constify the pathname passed to ->iget(). Major cleanups of the iso9660 filesystem; it would use insufficiently dimensioned stack variables and do compares in a rather inefficient manner. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
