13d9a660ca Zeroing out memory before using it can be so important. 2007-01-19 14:44:59 +00:00

d6909f65f0 Actually, it's probably safer *not* to leave child processes hanging 
around which still hold pointers to variables belonging to our parent...

4256b3338a Split random number generation out into core/random.c, and create the 
correct prototypes for srandom(), rand() and srand().

8bb9f726a0 When an async operation dies, orphan its children. 2007-01-18 22:36:57 +00:00
Michael Brown
6d4e37cf42 Move include/malloc.h to include/gpxe/malloc.h, since everything in there 
is now gPXE-specific.  (The standard malloc() et al have been in stdlib.h
for a while).

Add free memory counter.

35776f481c Don't always zero memory in malloc(). This saves around 2us on a 
full-length PKB allocation.

0b11733b75 Replacement for fetch() which operates asynchronously and identifies

544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously 
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).

4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.

dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.

f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.

83b7933f8a Damn it; my lovely resilient scheme falls down when you have a protocol 
that switches from line-oriented to byte-oriented partway through, such as
HTTP.

e2c0055e23 Let ifmgmt.c take care of calling efree(), since it's the once which 
took out the contract to eventually call efree() when it called fetch().

Maintain the most recently loaded image at the start of the list, so that
imgautoselect() will pick it.

67aedf34fa Use systematic names for XXX_IMAGE. 
Add scripts as an image format (since it's trivial to do).

475d6d1f7c fetch() now knows nothing about struct image; it simply loads a file and 
returns the allocated buffer.

f59ad50504 Provide registration mechanism for loaded images, so that we can e.g. 
refer to them by name from the command line, or build them into a
multiboot module list.

Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.
