+Subject: [PATCH] Fix bug in file shifting that could cause conflicting PT_LOAD
+ segments
+
+When a section in the file needs to be enlarged (e.g. to accommodate
+setting a larger RPATH), shiftFile() is used to shift all content
+following the growing section to a later position in the file.
+
+Commit 109b771f53ee3d37ede8c0f165665605183c0975 introduced logic to
+ensure that, after the segment split, no sections span multiple
+segments. This is done by sliding the portion of the segment after the
+split point later in the file, then adding a new PT_LOAD segment that
+contains the preceding data plus the extra room that is being added. The
+existing implementation does this by simply adding
+`extraPages*getPageSize()` bytes to the number of bytes ahead of the
+split point in the segment.
+
+However, this approach can result in two PT_LOAD segments that overlap
+when page boundaries are taken into account. As an example, this PT_LOAD
+section (taken from a Python 3.10 binary):
+
+LOAD           0x0000000000000000 0x0000000000400000 0x0000000000400000
+               0x0000000000000948 0x0000000000000948  R E    0x200000
+
+is split into the following two sections:
+
+LOAD           0x0000000000000000 0x00000000003ff000 0x00000000003ff000
+               0x0000000000001594 0x0000000000001594  R E    0x1000
+LOAD           0x0000000000001594 0x0000000000400594 0x0000000000400594
+               0x00000000000003b4 0x00000000000003b4  R E    0x1000
+
+Note that the two PT_LOAD sections both contain the memory page at
+address 0x400000. The Linux kernel's ELF loader (at least as of v4.18)
+does not accept this as a valid ELF executable, triggering a segfault
+with si_code=SI_KERNEL immediately when the binary is executed.
+
+The fix here is to set the length of the segment that comes before the
+split point more carefully; instead of adding `extraPages*getPageSize()`
+bytes to the portion of the segment that came before the split, the
+actual number of padding bytes that were needed (before rounding up to
+the next multiple of the page size) are used. This avoids the overlap
+in the PT_LOAD segments and makes the output files executable again.
