Also, it can't be that hypothetical if it has been proven to work. It is the big/gigantic sytems that will be affected by these patches not so much the piffling little stuff like my MacBook Pro. I can handle a performance hit knowing about it now but can the big guns? <- Rhetorical!

But unless one has experience of writing kernels and OSes then one can't possibly know how difficult it is to create patches, (that will inherently give a performance hit just to _correct_ a deliberate manufacturing fault for profit), that will not slow things down too much.

Apologies for this newbie question. We have inherited an IBM p5 520 (9111-520) running AIX 6.1.0.0 which seems to be the base install and no further patches installed. Is this vulnerable to the Spectre/Meltdown threat? Are patches available? Looks like AIX 6.1.0.0 went 'end of support' in... (8 Replies)

STG-SQUASH(1)							   StGit Manual 						     STG-SQUASH(1)

NAME
stg-squash - Squash two or more patches into one SYNOPSIS
stg squash [options] <patches> DESCRIPTION
Squash two or more patches, creating one big patch that contains all their changes. In more detail: 1. Pop all the given patches, plus any other patches on top of them. 2. Push the given patches in the order they were given on the command line. 3. Squash the given patches into one big patch. 4. Allow the user to edit the commit message of the new patch interactively. 5. Push the other patches that were popped in step (1). Conflicts can occur whenever we push a patch; that is, in step (2) and (5). If there are conflicts, the command will stop so that you can resolve them. OPTIONS
-n NAME, --name NAME Name of squashed patch. -m MESSAGE, --message MESSAGE Use MESSAGE instead of invoking the editor. -f FILE, --file FILE Use the contents of FILE instead of invoking the editor. (If FILE is "-", write to stdout.) --save-template FILE Instead of running the command, just write the message template to FILE, and exit. (If FILE is "-", write to stdout.) When driving StGit from another program, it is often useful to first call a command with --save-template, then let the user edit the message, and then call the same command with --file. STGIT
