Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

If the aarch64 builders for CentOS 9 or Red Hat Enterprise Linux 9 switch to 4K pages, this bug will also affect the Emacs package there.

+++ This bug was initially created as a clone of Bug #1974244 +++

The emacs binary from emacs-nox-27.2-2.fc33.aarch64 cannot start in a chroot on Red Hat Enterprise Linux 8 because it assumes 4K pages:

openat(AT_FDCWD, "/usr/bin/emacs-27.2-nox.pdmp", O_RDONLY|O_CLOEXEC) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=10124128, ...}) = 0
read(3, "DUMPEDGNUEMACS\0\0(\304wp;D\330G%\f\265\337\214\264VO"..., 80) = 80
mmap(NULL, 10124128, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xffff92240000
mmap(0xffff92240000, 6946816, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0) = 0xffff92240000
mmap(0xffff928e0000, 90112, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0x6a0000) = 0xffff928e0000
mmap(0xffff928f6000, 3087200, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0x6b6000) = -1 EINVAL (Invalid argument)

Map offsets and addresses must be a multiple of the page size.

I believe this was fixed upstream with this commit:

commit 216c65b135c2b0be7e048cdc6683873b03b99b9a
Author: Lars Ingebrigtsen <larsi>

    Use a 64KB page size for pdump
    
    * src/pdumper.c (dump_get_page_size): Use a 64KB page size on all
    architectures, as this many vary between systems (bug#47125).
